I disagree, while I personally don't care about romance in media or just in general, this persons point is just plain stupid.
Ballister and Abrosious are not a problem at all? It shouldn't matter that children are learning about lgbt through a movie rather than through their parents, thats quite the same as just saying that romance shouldn't be in movies marketed to children at all without the parents explaining it. The characters being different genders doesn't change anything it's just a closeminded world view that makes this person think it does. Either he's simply stupid or he made this as ragebait, because if your followers request a Nimona video and you don't want to do it, JUST DON'T. You don't need to make a video specifically for telling them you're homophobic??? Seems like a desperate attention grab to be honest.
