David Bronson explained to me that there are things that are not worth the trouble to argue with people about. It is that certain things are set in their DNA. {I was asking about the conflict between Israel and the Muslims.] But this can be applied across along long lines of issues.
It is best just to learn Torah and see what the Law of God has to tell us and to recommend to others to do the same.
Stll, with all that there is an "inyan" [a thing] about to "object". That is even if no one will listen, still one must object to wrong--at least to make one's position clear. [That is from the event of the Concubine of Giva. What I mean is on the second day of the war, (end of Book of Judges) God was asked if to continue to make war on Binyamin, and He agreed. Why? Because no one in Binyamin objected to the murder of the concubine. To punish the evil doers was not the issue. The issue was to punish the whole tribe because they did not object to evil.
However, I still think this is a one time event. You object and make your stance known and then get back to learning Torah.]
