one important idea of Rav Nahman {of Uman and  Breslov}is that not everyone is fit to rebuke, o even though it is one of the 613 commandments to rebuke anyone who is not acting properly, still not everyone i able to give rebuke. For by rebuke that is not proper one can make things worse.  However  "מחאה" is different than rebuke. That is the need to object  in public to actions that are not right. Like in the incident of Kamza and Bar Kamza. One person was invited to a wedding feast by accident. There was a mixup of the wedding invitations. so an enemy of the family was invited to the wedding. When he was thrown out many of the religious scholars were there but did not object. Because of that incident the sages aid the second Temple was destroyed

When a woman or a slave cause damage, Gemara in Bava Kama [perek hachovel] page 87:a.[בבבא קמא פז ע''א] Rambam laws of damage 4 law 21

Ideas in Shas

 When a woman or a slave cause damage,  they do not pay [because they do not own property].רמב''ם הלכות חובל ומזיק 4' כ''א My question here is why should not she sell her ketubah for the benefit of the person she damaged? (After all, someone could buy it for a reduced price because the husband might die before the wife, and then the buyer would collect the whole amount. Or the husband might die first, and then the buyer would collect nothing.)

The Gemara in Bava Kama [perek hachovel] asks this question about property she owns but which is not written in the ketubah. [נכסי מלוג] But that suggestion is only going according to Rav Huna ben Yehoshua who holds even if she would sell that property, the fruit would still go to her husband. [That is how Rav Shach answers this question:  why the Rif, Rambam and Rashi leave out this suggestion of the Gemara?] But I ask about selling the actual ketubah. . And the money from that buyer would then belong to the wife as the Rambam writes in laws of marriage 22 law 27. And then she would then pay for the damage that she caused

 When a woman or a slave cause damage,  do not pay [because they do not own property]. My question here is why should not she sell her ketubah for the טובת הנאה ? The גמרא in  בבא קמא פז ע''א ] asks this question about property she owns but which is not written in the ketubah [נכסי מלוג]. But that suggestion is only going according to רב הונא בן יהושע who holds even if she would sell that property, the fruit would still go to her husband. [That is how רב שך answers this question:  why the רי''ף רמב''ם ורש''יleave out this suggestion of the גמרא?] But I ask about selling the actual כתובה. After all, someone could buy it for a reduced price because the husband might die before the wife, and then the buyer would collect the whole amount. But thee husband might die first, and then the buyer would collect nothing. And the money from that buyer would then belong to the wife as the רמב''ם writes in הלכו אישות  כ''ב הלכה כ''ז. And then she would then pay for the damage that she caused 

בבבא קמא פז ע''א

כשאישה או עבד גורמים נזק, לא משלמים [כי אין להם רכוש].(רמב''ם הלכות חובל ומזיק ד' הלכה כ''א) השאלה שלי כאן היא למה שהיא לא תמכור את הכתובה שלה עבור טובת הנאה? (כי יכול להיות שהבעל ימות לפני האישה, ואז הקונה יגבה את כל הסכום. אבל אם האישה תמות קודם, אחר כך הקונה לא יגבה דבר.) הגמרא בבבא קמא פז ע''א  שואלת שאלה על הרכוש שבבעלותה אך אינו כתוב בכתובה [נכסי מלוג]. אבל ההצעה הזאת הולכת רק לפי רב הונא בן יהושע שמחזיק אפילו אם הייתה מוכרת את הנכס הזה, הפירות עדיין היו הולכים לבעלה. [כך עונה רב שך לשאלה זו: מדוע הרי"ף רמב"ם ורש''י משאירים את הצעת הגמרא הזו בחוץ?] אבל אני שואל לגבי מכירת הכתובה בפועל. הרי מישהו יכול לקנות אותו במחיר מופחת. הכסף מאותו קונה היה אז שייך לאישה כמו שכותב הרמב''ם בהלכות אישות כ''ב הלכה כ''ז. ואז היא תשלם על הנזק שהיא גרמה

ten times review

 When I was in Shar Yashuv I heard this idea about review ten times and I am seeing that this helps. It was how I used too do the Maharsha and Pnei Yehoshua and the other achronim like Rav Chaim of Brisk and Rav Shach I have started to see that this idea help also for  Mathematics. [I do not mean to diminish the importance of fast learning also- but I think the main emphasis ought to be on lots of review and in depth learning as my son Izhak told me 

children need a wholesome environment

 One reason to obey the excommunication of the Gra is that children need a wholesome environment that you just can not find anywhere outside of the straight Litvak world.  You might be inspired by Rav Nachman and that is fine. But there is a difference between what you can learn and the  environment in which children ought to be raised

[Anyway my opinion is that Rav Nahman himself was not an object of that "herem" because that  was more specific than most people realize. To see this you ought to look up the actual language of the herem which I found in one book that contained  the actual language plus the testimonies that were collected in Villna before the publication of the herem.

It should not matter what the herd thinks. What should matter is what is objectively true

 I was going to Uman Ukraine every year for Rosh Hashanah and staying for some months and sometimes longer. They used to have a very nice celebration on may 9. Every class in the local schools would put on its own presentation for the victory over the Nazis. This went on the whole day. But at one point, that was silenced. Then one after the other, all the statues of WWII heroes were taken down. Then even the central Russian orthodox church that was packed every  Sunday was locked and shuttered.  

It is almost as if they regret their victory over the Nazis 

 I think the  approach of the Litvak world is the right thing: to learn in depth in the morning and to learn fast in the afternoon. The learning in depth I think should be with ten times review of every section. Even though learning with depth and understanding should be the main emphasis still there is a place for fast learning--jut saying the words and going on. 

Counterfeit Torah

 Most of what is sold as Torah nowadays is not Torah at all. It is a fake and not authentic. This is the very reason for the signature of the Gra on the famous letter of excommunication--to warn people to stay away from Torah of the Dark Side.  The is idolatry which dresses up in Jewish rituals in order to seem kosher
