I do find it funny that the moment two blokes have a close friendship on screen people are confidently declaring that they’re gay all over social media now, as if blokes aren’t able to have deep and meaningful friendships that aren’t sexual at all.
You do make a good point that any two close male heterosexual friendships being labeled gay is a problem. Its important to show that as well. I feel like some pairings have friendship vibes than others but that's the fun of the debate.
But what I think this video shows is how important representation is. Since there was no queer characters in Star Trek people made their own in their fan fictions. These become wildly popular and influential at fan conventions, zines and the internet. The whole genre is still referred to as Slash Fiction for the most popular pairing Kirk/Spook fiction. These types of fan fictions influences future writers, actors and showrunner who made it a reality. That is what I think is interesting about this video
