One for communists is hardly any different [to one for nazis] as far as I'm concerned.
What do you expect to happen when you call a group of people "hardly any different [to nazis]"?
Communism does not advocate genocide any more than capitalism does. A capitalist society may commit genocide, a communist society may commit genocide. Neither are required to by their economic systems.
National socialism directly advocates for genocide.
It's a ridiculous statement to compare communists to nazis and it's not surprising that insulting communists like that will get you banned.
(Adding islamism to the comparison just makes the statement even more bizarre.)
So many people here trying to argue dictionary definitions and hide behind technicalities to make their little slice of authoritarianism better than that other slice of authoritarianism.

Good lord, look at the replies to this post. Even being called out on the behavior, they still cant resist slapfighting over silly technicalities and dictionary definitions.
Yeah no shit if you go to the communist instance and say communists are just as bad as nazis, you're gonna get banned. You even admit to doing this specifically to get banned in your own comment.
Like even though I'm a socialist, I think the guys at lemmy.ml are a bunch of nutjob tankies, but banning people that come to their instance just to be a troll, insult people and purposefully try to get banned isn't actually a bad thing.
It's maybe hard to realize but these moderators wants an environment where their users never see an uncomfortable opinion that upsets their users.
As an adult, I don't have a problem with different opinions, but my teenage son has massive issues with it. He wants to go to war with people over opinions, and if they don't agree with him, they are stupid. So I think it's a maturity thing.
Sooner or later, you realize that people have different opinions, and censoring them doesn't make them go away. The ability to discuss different opinions is what makes someone mature.
Anyway, I can absolutely understand why they don't want to moderate difficult discussions. That's a lot of work.
