while true that leftist infight a lot, the right most definitely don't have solidarity with each other, they fight even more, staying true to their ideology, they fiercely compete with each other, plot, backstabbing and so forth, this increases further the farther they are from reason like qanon. the single common point is that they obey and defend capital and when its threatened, they can momentarily join hands to purge the threat.
the tricky thing with leftist is that we lack this bond, the thing that "holds up" is a world that doesn't exist.
