For me that would be fanboys/fangirls.
They don't talk about actual logic at all. I know anime doesn't follow logic most of the time....but this takes the top place....far worse than the non existent logic...
I can deal with fans better than haters. But in order to hate something, you need a reason for it and fans the reasons aren't evident unless it's glaringly obvious by their likes and dislikes in real life.
