The unfortunate thing is that people tend to be judgemental, so if you don't fit what their definition of a label is, you can be called out or even ridiculed for it.. It can have the effect of polarising people.
Because of this, I don't like labels. I prefer to think of people as people, rather than attach a label to them. I think there is so much variation and individuality, labelling things just doesn't work. Instead you should just take time to get to know someone, rather than rely on labels which might just confuse or lead to misunderstanding
