LoL a dead game......O_o?1: Kids play the game.
2: Theres a difference between a taunt and the outright abuse/primary playschool abuse that some players keep launching,
Just look at how LoL has suffered because of many people with attitudes similar to yours , as first of you scare off all the kids/Parents stop their kids playing, That leads to higher queues , Higher q's leads to people giving up waiting = a dead game.
You then refer to the 90s/00's well thats funny as my brother says that most companies back then took a very harsh view of online abuse in their games Although he also pointed out some films which although great back then are actually deemed racist now.
So you potentially place the blame on an education system that is turning out children who are basically taught to be "offended" at just about everything that doesnt fit the view they were taught (I say this as the UK had a "no losers" period in schools where even sprotsdays had no 1st place or last just participants)
And those "kids" are probably the worst offenders of taunting lol ^ ^
