This is news to me. I am 24 and I occasionally get disbelief. Most of the players are just a little surprised and then are normal after that. No one has ever been rude. Maybe I have not visited such servers. As a side note, I have played with a few older players who were around the ages of 40 and 50 as well and never witnessed any players being rude to them. Sure some fifteen year olds are uncomfortable playing with a fifty year old but that's about it as far as I have seen,
