I preferred you with Jaime, though that just might be me being nostalgic for the season 2 live threads and the Bluepulse community on Tumblr
This is all guessing, so apologies in advance if it isn't true: you subconsciously compare /co/ntent to current American politics. When you see a gay character, you assume they were created to satisfy current trends or appease a certain group of people. This can cause the character to feel inorganic and forced. Secondly, you might also think the inclusion of a gay character, especially in a children's series, is propaganda and shouldn't be shown to children.
With anime and manga, you don't think things done are for political reasons (they might be, but you don't know that since you're not privy to Japanese politics). So when you see a gay character, you probably assume it's because the author personally wants to include them. You also don't feel their inclusion to be propaganda, because you see anime as being more mature. For sure, some kids do watch anime, but it's mainly adults who do, so you don't get the same feeling of "having to shield their eyes from this degeneracy." Lastly, when an anime or manga features a gay character, often times you know in advances that it does. Either the series will be labeled as a yaoi, shounen-ai, or fujobait—or maybe even has an art style that lends itself to be seen that way, so you can easily avoid that stuff. Meanwhile with cartoons, gay characters aren't introduced/revealed until later in the series, so it's a complete surprise and thus might make you feel betrayed/led on.>>115862404
With that though, most of the readers are fine with homosexuality in general. I mean, for fuck's sake, it's literally a story about accepting homosexuality—of course anyone reading it to the end is probably fine with it. The shitstorm is more about a lot of these readers feeling that Taichi being gay was an asspull or upset that Futaba lost the Taichibowl.
