When I was a kid watching TNG with my parents, my father would sometimes say things like “Man, that guy is too handsome” when Riker was on screen.

The TNG cast is pretty human. They don't avoid anger, happiness, frustration, empathy, sexual tension, etc.

To the chuds of 4chan, showing a normal range of human emotion is over emotional, which this greentext is mocking.

There's also:

• The Host which has Crusher dealing with falling in love with a Trill who moves hosts. It can be seen in some very specific ways as a trans allegory and just challenging heteronormative assumptions about love and attraction.

• The show really pushes a lot of 'Found Family' stuff which ends up being super popular in most LGBTQ+ media because we're disowned by other people. (Data accepted and accepting himself as part of the crew, Worf and Alexander aren't too awesome but Deanna steps up a bit there. You've got Wesley who's kind of adopted by most of the upper ranks after a while.

• TNG is purely "Infinite Diversity in Infinite Combinations" which people see as gay agenda because they wanna collapse anything pro-diversity as just being LGBTQ+ because they have fragile pathetic minds.

• Q is aggressively queer coded. The hyper dramatic and flamboyant personality, the penchant for being a theatrical whore, openly flirting with Picard (and Riker) in such a way that you genuinely aren't sure if he's joking or not, he rejects every type of rigid norm from humanity, Voyager and a few other things even hinted in such a way that due to his ability to change form he's above gendered norms too and sort of gender fluid. Not to mention being the campiest motherfucker this side of the Alpha quadrant. "It matters to me. YOU matter to me. Even Gods have favorites, Jean-Luc. You've always been one of mine." There's also his deep fucking loneliness, something that a metric fuckload of people in the community suffer from. Part of a whole but ostracized and on the outside? Yea.
