No, I think you're right. People do get way too defensive if someone doesn't like what they like and often seem to consider it a personal judgment when it really isn't.

I can understand why people get defensive sometimes because there are a lot of people out there that think "I don't like this" means "therefore nobody else should and you're a bad person if you do." That isn't the case with everything though.

Like something or don't like something - it's all just opinions. Just let people like/not like stuff in peace.
