Anger against children who play FORTNITE?

Be Fortnite is in the hype and 90% of the community consists of 10-15 year olds. I get excited how kids talk and wear Fortnite merch. You can also tell from their behavior that they play Fortnite and that triggers me badly. Can I get rid of this "anger" somehow?

I would say that stops at age 14 (I'm 15 myself).

I also try to avoid them. What works best:

Never play something "fill up" (e.g. Fill up creatively or fill up teams)
Mainly only play with friends you know and who you can stand in Fortnite
If creative, then only alone, trust me. (I played fill-up creatively myself, a short time later… ALT F4)
and play more arena. Competetive usually only play decent people (if you have at least 4k points)

Oh yes, there should always be something soft next to you. Or put a punching bag down, that helps xDDD too
