What your thoughts on lolis and traps?

Answer the title because I wanna know as well I'm not sure if Im overreacting or not. I have an cousin who is a minor and I think he has an obsession with lolis and trap.

He obsessively talk about lolis and traps, make repeated texts and faxe about lolis and traps, focus on positive or the negative of lolis and traps.

When I said lolis and traps are weird he got defensive and started saying that I was mad because he been on the internet a long time. Which i guess was true but I just felt comfortable.

Is this okay? Am I overreacting? As well what your thought on lolis and traps?

If you read all this thank you and sorry
