That's quite a disquisition over several posts but understandable since the word limit on single posts seriously impedes debate.

I do not condone the shutting down of debate nor do I condone violence.  A cursory view of the daily news shows that violence and disruption is not exclusive to the left.  When neither political party is acceptable it is not unreasonable to vote for a fringe candidate to give them voice.

The right have greater means to buy influence including legislation favourable to their interests and to promote their ideas through lobbying, political donations, the media, think tanks and special interest groups often done furtively by people like the Kochs and the Mercers.

The left have little countervailing power and lacking any voice in governance naturally push back often in unacceptable ways.  Perhaps limits on lobbying, an end to recognizing corporations as people and restrictions on the use of money in politics would improve the situation.
