The reason you can't keep a post without it being flagged is because you're spouting nonsense and attacking people.
It has nothing to do with which side of the political spectrum you are on.
Your comments are downvoted because you have written in an attacking, nonsense style. They are low quality comments, and HN is a place for higher quality discussion.
If you wrote a "liberal extremist" comment in the same style, that would be downvoted as well.
Attacking other users ("SS thugs like you") is especially unwelcome here.

As someone generally critical of radical left-wing politics (in fact, any radical politics), you are not doing yourself (or anyone) any favours by using ad hominem arguments like this. Please just stop.
