As a teenager, I hear and see this happen quite often. In fact, I see even adults making this mistake sometimes. Is differencing opinion, and fact. Teenagers will often say "Man that was gay" And someone else will respond as "That's not gay, it was cool." We state it as if it was fact, and nothing may change that. And sometimes, other people will get into fights over it.
I see this in adults, but it's not quite as vulgar or obvious as when teenagers do it. I mean, I'm not perfect, in fact I do this myself. But why? Why do we do this? We think just because we don't like something, it's fact that it stinks. Can't you just have an opinion on something and let everyone keep there's? No. But that's our corrupt world.
In the teenagers world, I see bullys/tormentors kill off opinions all the time. It's horrible to see. And I try to stand up for some of those kids. But, it doesn't stop kids from generating opinions, or arguing or standing up for themselves because of it.
Guys, it's just opinion.
