Is toxicity really such a bad thing to have in games like these

The whole dunkey thing is going on right now so i feel this is the best time to post, is being toxic really such a bad thing. One thing people seem to forget is people love bragging and talking shit now i'm not saying they shouldn't be reported for doing so, but this game and many other would die out if people felt like they didn't have something up on another person. A moba game that came out a little while ago, Strife had no all chat. I found the game to be very fun, but in its response in trying to handle mean or unruly players they got rid of all chat, which made communication in the game sink to the point where i could go a whole game and my own teammates wont say a word. That's a terrible thing to have in a game. People also love a challenge, don't tell me you never felt good escaping from a 5 man gank and typed out "not even close" its almost too good to resist sometimes, especially when they have been unruly as well. I like to compare things to basketball, you always have that one dude who talks mad stuff all game he gets dunked on and everything he says means nothing for the rest of the day priceless, like a guy who escapes a gank every time says "not even close" then gets hit with a jinx rocket. it feels so good to shut them up. But like i said this doesnt mean people shouldnt be reported for being dicks, but a majority of players have been that jerk and have been shut down as a result, one last comparision, would people still watch stupid reality tv if it had no drama, no.
