Man, the discussion earlier about not having more than one space marine army has me having a bit of a big thunk about having chosen to do up my Space Marines as Blood Ravens. I love the lore and the memes, but at the same time, I could instead do some yourdudes, with something like, I dunno, an Irish themed custom SM chapter or something similar. Kinda like how the the Carcharodons are vaugely Samoan themed. It might be fun to have created a chapter out of whole cloth.
Having said that, I am now realizing I have no fucking clue about Irish lore and celtic mythology to do something like that. (And, doing a bit of a search, apparently the Storm Wardens are basically "Celtic Blood Ravens only not" so...)
Edit: Also, the 40klore subreddit, which is controlled by sigmarxism, wants you to know that Real Communism in 40k has never been tried before.
