Well, that comment by nutomic is certainly unfortunate, but I don't think that's exactly what people are thinking when they complain about tankies. The Soviet Union banning homosexuality is certainly also unfortunate, but it's not different from what every other country on Earth was doing in the 20th century. It's not reasonable to expect communist countries to get social issues right on the first try and attach their failure to do so to their economic organization. My country also banned homosexuality, for the record, and we absolutely were not communists.

It also just happens that most LGBT people I know, by a landslide, are marxists, because it's the logical consequence of applying to capitalism the same questioning that allows breaking free of the cisheteronorm. Sometimes economics and gender/sexuality intersect in interesting ways, and to an extent attempting to stomp out marxist ideology also often inadvertely makes the place hostile to LGBT people.

You can argue that "tankie" only refers to toxic, LGBTphobic marxists such as nutomic right here, and I mean, fair. But I'm complaining about the Lemmy community being incessantly hostile to people and communities that are outside of a very narrow worldview that you can really only find in terminally online people. 99% of the usage I have seen of the word "tankie" on Lemmy has been for this, It is keeping people out of the norm away from this platform and, as seen with the way so many users harassed drag, for good reason.
