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.)

But then why wouldn’t the board say exactly why Altman was removed?
