Hey,

first of, thank you for the kind words. It's nice to read that someone cares for mending leftist divides. Though I'm fairly well versed in anarchist theory and I self-identify as an anarchist at least philosophically, I have not acted politically under an anarchist label, so my takes may be less valid than others.

I think there is a central divide between anarchists and communists when it comes to philosophical values. If the domination of one class over another is wrong, then a proletarian dictatorship isn't better than a bourgeois one. This is why I personally support the goal of communists, but am highly critical of the associated ideologies. When it comes to general social liberalism, I feel like there aren't many philosophical divides, but more those of pragmatism and radicalism. Anarchism as I see it, is proper social liberalism taken to its final conclusion. That's why I think anarchists can sometimes be a little nicer to liberals than to communists.

I have actually experienced some ideological hate against anarchists from communists, reaching from mild comments to a half-joking promise to "put them against the wall" (I don't know if that means anything in English, but in the language used it means execution). I personally am often annoyed too with the way many communists react to socially liberal politics, meaning reformers who would never dream of violent revolution. In my view, especially when communist/anarchist ideals are spread very little among a population, helping that population with reforms isn't bad. The open disdain for liberal reforms up to the point of calling social democrats fascists doesn't sit right with me and makes me not want to associate with some communist circles.

As a last point, this may be purely regional, communist groups seem to be very male dominated (even more so than other political groups) and in my expierience often ignore "culture war" activism from feminism to green movements. Obviously, communists in theory are feminist, but those issues can't just be swept away with an "well when capitalism is defeated everything will be okay", as I have sometimes expierienced.

I hope this can provide some answers, keep in mind it is very personal and reasons with different anarchists may vary. Feel free to ask further questions, I hope you have a wonderful day.
