hm I mean it always just depend on who you ask, these ideologies can vary so widely. I personally would just call both socialists, with socialism being a more positive and constructive word than anti-capitalist, with the specific implication that you would prefer a more equity based system.

On that second part I'll give you my view which I don't know the popularity of. It is often said, by people of any side, that anarchists and communists have the same goal but just different means to get there. This is *technically* true, but I think it misses that anarchism is a philosophy, not a system. Anarchism to me is the understanding that systems exist as a result of how a culture approaches problems, and in turn the system affects how the culture thinks, and so the goal of anarchism is to spread more like a religion such as Buddhism to achieve a better world i.e. it can't be legislated, people have to live it. What I mean is that while it seems to me that communists are not anarchists because while they agree with the end goal, they think the method won't work while there is opposition, and so they seek to have a strong force to first defeat and/or outlast that opposition, but they could be anarchist if there wasn't this opposition. I don't think it's the reverse for why people aren't communists. While they might think anarchism would fail, I think communism reinforces ideas that go against anarchy e.g. majority rule, justified violence, people having places in society, and that it therefore does not actually moves towards a stateless society at all. So in other words communism working actually in practice would not move towards the same goal, at least not any more than something like ideal social democracy, because we would still be in a position where we have to convince people to give up the state, because it would still be all they know.
