Point taken, though I see no issue with labeling. I assume bronies call themselves that to instantly convey that they like MLP, same reason a Christian conveys they have biblical faith or an African lets you know they're from Africa.
You can't label yourself as African. That point is invalid and I am now disregarding it.
Now, I can understand labelling yourself stating you're of a certain religion (Christianity, Judaism, etc,) but
you're labelling yourself from watching a television show. This is something nobody should care about in the slightest, it shouldn't even affect the way you look at the person. You can bring up that I'm hypocritical, but I just want to go on the internet without being bombarded by girly ponies everywhere.
