I am willing to accept any subject for debate. If the outcome is that we fail to settle our differences, so be it. But that applies to menchliche debate. When your difference of opinion with me goes beyond protest, and enters the abyss of violence and intentional harm to person or property, we are no longer debating but at war. And war means that the stronger force will win. Maybe not the correct one, but the stronger one.
The issue with the protests is not that these groups adopt an opinion that is worth questioning, or even unpopular. It is that they deteriorate into the jungle mode, mob mentality in which there are no longer any barriers to their most animalistic and primitive drives. These protesters, who are touting the banner of Torah learning, kedusha, etc., are behaving in a completely goyishe manner, abandoning the Torah learning they profess to value, and engaging in harmful activity and chilul Hashem. These protesters do not bring awe and reverence to their lifestyle, but rather disgrace and humiliation. One cannot look at this and feel any positive feelings for those that taught them this behavior.
The mentality of their violence is not excused by the merits of their issue. Sorry, but I judge this trend by the ugliness of it, not the cited reasons for it.
