The Democratic People's™ Republic of Tankiejerk

You can see on ProleWiki what Lemmygrad.ml's stances are, in their words, and why. Their article on the Russian Federation backs up what you've said, they believe it is extremely reactionary with horrifying treatment of LGBTQ people and is currently ruled by the Nationalist party, but critically support Russia insofar as it opposes Western hedgemony and Imperialism, and no more than that.

Critically, Lemmygrad, Hexbear, and much of Lemmy.ml see Lenin's definition of Imperialism as the number one obstacle in Socialism's advance, that is, the state in Capitalism where Imperialist countries export machinery and finances to the third world in order to super-exploit outsider populations for super-profits domestically. This is a necessity within Capitalism to combat the Tendency for the Rate of Profit to Fall. It's the concept of unequal exchange.

Now, of course you do not have to agree with Lemmygrad or Hexbear or Lemmy.ml, but as someone who regularly sees these posts, there are no delusional posters who somehow think the Russian Federation is still Communist or that Putin is secretly rebuilding the USSR.
