@LukeAlmighty Trump is in office, but even so, the left still has plenty of power and influence. Much of which was gained with the help of such dirty tactics. Unless Trump obliterates them (which I doubt he'll manage to do), from their perspective political violence works. It has rewarded them with power, that they've still managed to hold onto even now. Hollywood, mainstream news media, universities, most big IT companies, and other multinational companies. So again, unless Trump destroys them completely, they have every reason to believe that political violence can help them hold onto power, and increase their power in preparation for 2028.
I sympathize with libertarian ideas, but as long as sociopaths and psychopaths exist in the world, I don't believe libertarianism could be fully stable long term. Not sure yet what approach is best. The only thing I'm decently convinced of is that a nation does need a decent amount of patriotism/nationalism. But what you combine that with can make a drastic difference in the end result.
