Nucleophilic... just because you're so disenfranchised and disillusioned that the opinions of others have no effect on you doesn't mean that others are the same way. Nor should they be. The world would be a horrible place if we didn't care about each other. Most people are impacted by what others think of them, to some degree at least, and as such things like what happens online(especially the 'go kill yourself' style of harassment) do hurt the majority of people.
Unless you're suggesting that everyone just mute EVERYONE every game, muting doesn't prevent harassment... it just stops it AFTER it has already started. Again, as people have been telling you for ages but you seem incapable of understanding: the mute button is not a panacea. It does not CURE the harassment. It doesn't make the person feel better, it doesn't heal the hurt that's been done. What it does is prevent it from getting worse. The mute button is a bandaid. It covers something that is hurt and prevents it from getting hurt worse... which is good, and should definitely be encouraged... but the ability to stop matters from getting worse does NOT justify the fact that the person did the action in the first place.
I'll give you the same example I gave you elsewhere that you refused to reply to:
If you walk up to me and stab me, and I leave and go to the hospital and they treat me and prevent the injury from getting worse... does that JUSTIFY the fact that you stabbed me?
The ability to stop matters from getting worse does not justify a person who chooses to hurt others. Regardless of if that hurt is emotional, psychological, physical, or financial.
