However you package it, the facts are that these people give public support to the murderers of our brothers. This support has a tremendously detrimental effect on yidden by changing public opinion (“there are even orthodox Jews who see that Israel is at fault…”). There is no defending that nor is there any justification. They are not part of klal Yisroel in any way. They have separated themselves by publicly siding with those who wish to annihilate us.
It is inexcusable and certainly not “kosher” to defend this evil behavior.
