Why are there so many "Was Historical Figure X Gay?" investigations?

Somewhat less sarcastically, particularly in this specific case I'm suspicious that this is in part to further tear the man down, above and beyond what his own known mental state did to him. Even years after his death, there are still quite a few places on the political map that despise and utterly loathe him, and will do anything to tear him down,*
particularly now that he's not around to defend himself.
And tangentially, the "Thread closing in..." stuff isn't particularly helpful, nor does it actually contribute anything to the topic of the thread.
