Is it normal for people to be singled out just because they like different things?

It is perfectly normal and people do that for one reason. This being that they are unable to step out of their box to experience something new. Everyone is unique in their own way and the best thing that you can do is keep feeding that uniqueness. Some people follow others, whereas some people lead. You should always lead

Yes, it's quite normal. Everyone has different likes and interests and sometimes those things butt heads. It's hard for some people to not be judgmental of others liking's or other things of the sort. So, to feel like you're not being apart of a group for feeling a certain way is completely normal. Not one person is the exact same.

Everyone of us has different opinions and i think there is really no one two people who has exactly the way of thinking and the same opinions. I think that's a good thing, that there is no one who knows it all. I think that there will be really times that what you think is different from what others think. Those situations call for everyone to have respect (especially for their independence and freedom to think for themselves and freedom of expression), openness and maturity. It is never all right to bully, use foul language, gossip or isolate person or groups of people just merely on the basis that you have a different opinion or different preference.

You should surround yourself with people who are accepting of you, no matter what you like. I know it might be hard to seek such circles, but do give it a try. People who discriminate you just because of things you are keen on are NOT worth your time.

It is very common for it to happen unfortunately. People often pick out differences, whether out of curiosity, or something worse. But liking different things is good. Try not to be discouraged away from what you love, the right people will only point it out out of kind interest
