I actually raid on occasion with some young players and they are on my friend list because they can both play and fit into the demeanor of the team. I have played with a few young ones who are too excitable and talkative, but by shear numbers, it is the cocky, mouthy 16 to 20 year old's that end up getting the boot from a pick up team. Many older players will show an upfront negativity to younger players based on their voice alone, but it is usually a matter of maturity than anything else that drives how people act. No older friend on my friend list bullies younger players in my lobbies as a rule. On the rare occasion it has happened, it is the mouthy ones that get removed. Do your thing and don't worry about the bullies. Just know they less of a person than you and move on.
