One could argue that advocating for anarchy is a dumb take in and of itself.Yes, reactionaries are a problem.
It kind of depends more on your point of view to view a take as dumb in the far left.
There's lots of infighting, but it can kind of be summed up as tankies vs anarchists.
I'm biased and I will say tankies make quite dumb takes. Some anarchists don't even view them as left.
I'm not going to speak for anyone else, since I am only me, but when I see things like that it doesn't make me want to join that side.
