It seems to me that self styled anarchists use the label because it's an easy, safe way of saying you're a bit of a rebel. It has a common, dictionary definition. At least in my country, you could shout that you're an anarchist from the rooftop and never lose your job.

The same is not true of Maoists, Trots, other kinds of Marxists. Nobody I've ever met claims to be one of those without having read some theory (the 'some' is variable, naturally). Claiming those labels brings heat and everyone knows it. If anything, I know more people who have read lots of Marxist theory who still don't claim the label because they know that it will put their skin in the game and potentially their job on the line.

Maybe I'm wrong but I don't think anyone would put quotation marks around 'anarchist' when describing or criticising e.g. Kropotkin. To me, it's more of a nod to the fact that 'anarchist' is often used in a meaningless way by people who aren't seeking accuracy.

They just want you to know that in an ideal world we wouldn't have a government or bosses or crime, etc, and everyone would decide all at the same time to share power and work together and all live happily ever after. Quite different to those who participate in direct action or the Catalan anarchists and Makhnovites of old. Or maybe 'anarchists' would like to cosplay as a violent revolutionary anarchist to achieve their goals but idk. That strikes me as more adventurist than anarchist even if both labels 'fit' according to the common psyche.

Like I said, as a broad descriptor, it's not a label seeking accuracy as it's been co-opted so many times. It's a label for those who want the aesthetics of being a revolutionary without risking their job or friendships. The quotation marks make it clear that neither real anarchists nor Marxists accept that breadth.
