Related to the topic at hand, the way MTFs are treated in gay male spaces online is probably completely different from how they would be treated IRL.
On occasion, I will see someone white knighting for troons by criticizing that gay men call vaginas gross because it hurts troon feelings and "not all gay men have penises." Of course, since this is on the internet, there is no way to know if the person saying this is actually a gay man. They probably are not. It is ironic troons want gay men to stop bonding over disliking vaginas, since that is kind of one of the few things all gay men have in common.
Another thing I have seen, primarily on Reddit, is an NSFW picture or video of a FTM in a subreddit that dedicated to gay men. These posts often get a decent amount of upvotes. Think of it like when a troon posts a shitty nail job on a nail art subreddit; they get showered in praise. I see three reasons for someone upvoting it: 1. societal pressure to conform to wokeness and pretend that the woman is a man; 2. the people upvoting are not gay at all, but are bisexual men or straight women; or 3. the person upvoting is a troon. It is an incredibly jarring experience to be a gay man scrolling through one of these subreddits and suddenly being confronted with pictures of someone with a hairy chest, beard, and labia, or worse, a testosterone-engorged clitoris.
Woke societal pressure may make some gay men feel obligated to at least make these women feel welcome in gay male spaces, but they would never consider dating one of them.
