People in this thread say they're sick of gays, I think they're really just sick of bad romance in cartoons. People fucking hate all the Finn/PB/Flame Princess shit, as well as the love triangles in Star Vs and Regular Show. As well as the rushed romance in Samurai Jack where they love each other so much they're to be married. I don't think people would care about Korra or PB/Marcy so much if they weren't just so... Poorly handled.
I mean, realistically, no one bitches about Pearl and Rose. That's a romance that works and it's rarely used as evidence as why people are sick of gay shit. It's usually stuff like Britta's French Muslim Taco that's put in those bait collages.
I mean, if you want proof it's shitty romances /co/ hates, look at the lesbian couple in Victor & Valentino and how people hate them because they contribute nothing to the story and are suddenly given focus. People used them as bait for weeks. Now look at the two gay cops at Gravity Falls. No one brings them up once, because their "way too close for comfort" relationship was pretty evident from the get-go.
Anyway, that's my two cents.
