There's also evidence of sports fans and music fans and film fans doing all those things, and people involved in all those committing suicide.
Does that make those other things toxic? On a purely comparative level, gaming is probably less 'toxic' if you go just by the worst things done by its fans.
But is gaming at fault here? Or maybe "gaming personalities" are simply people for which real life sucks, so they try to alleviate their pain by gaming a lot? Maybe gaming was the thing that delayed their suicide by months/years?
