For me it's that anarchists are moral purists which often dont align with a leftist slightly less radical or outside of their worldview, in a society that will likely never accept anarchism.
I believe in leftism now, as opposed to "not voting because voting means you believe in people ruling over you." Which is the summary of many anarchists have told me.
Other than that I dont mind anarchists, but if we want change, participating in current society by voting and organizing now is the only way.
