I get what you’re saying but I don’t agree in this context. Especially when it’s what pizza cake is known for. If you don’t say you’re not something, then you’ll be called something anyway. That’s probably what the commenter was saying. With that being said, just because someone says I’m not sexist doesn’t automatically make them sexist believe it or not. If you don’t not know the person and you’ve never seen how they interact with people and you’re going off of one sentence, that’s not very reasonable, don’t you think? There’s a difference between saying I’m not sexist but I don’t like women and I’m not sexist but I don’t like her comics. In the eyes of pizza cake fans, it’s the same thing.
