When it came to Sheriff Blubs and Deputy Durland, if you were suffering from gay brainrot back in the day, you could say it was an early example of dudes forcing gay stuff into a cartoon, but for the most part they were meant to be comic relief characters more than anything else. You really weren't meant to take them seriously like Ruby & Sapphire, for example.
What happened at the end is that Blubs and Durland professed their love for each other and then fired a cannon, as a way for the animators to throw the shippers/fujos on Tumblr a bone. (You know, because Blubs x Durland is "cannon"?) I dunno why the fujos wanted two hillbilly cops to profess their love to each other, but this was 2015/16, where the gays were high off Jailbreak and #LoveWins, and wanted anything and everything to be gay.
There actually were moments where Disney put their foot down, like when the Love God in Season 2 originally had a trans gender symbol on his necklace that got changed to be both a male and female gender symbol, and they removed a small gag where one of his potions caused two girls (I think) to make out. That was in late 2014, when gay stuff in cartoons was starting to ramp up after the progressives were emboldened by GamerGate brainshock.
