(1)(The main thing is not to affix blame on anyone but rather to work on self improvement and to stay away from evil people that will harm you and your family if given half a chance. This is part of the Mizvah of not saying Lashon Hara which comes in the same place in the Torah along with the mizvah do not stand by the blood of your neighbor. That is there is an obligation to warn people about dangerous people.)
(4) [When the Rambam Maimonides refers to Physics and Metaphysics he says he is talking about these subjects as understood by the ancient Greeks.] My opinion about it is it would include Kant and the general school of German idealism.[Schopenhauer, Hegel, Fichte. Some people go with Hegel. and think of him as even greater than Kant. I can not do that. But others in the German school itself thought low of Hegel. I can not do that either.
My impression always was there is a big difference between authentic Torah at Lithuanian yeshivas and the false Torah of the Sitra Achra of the religious world. The main difference is that the ultra religious world makes up tons of rituals which have nothing to do with Torah and they claim it is Torah. The Lithuanian world tends to focus on what the Torah actually requires.
