I sure do. But just because someone says "natural selection" doesn't mean they should be killed. In fact, since we're talking about mental weakness, it's more than plausible that he was talking about suicide.
I mean, your comments seem to give off the impression that you are unfamiliar with the term. People who wear glasses have bad vision. They invented glasses to make up for this. That's natural selection at it's finest sir, the ability to adapt. If you have a mental weakness, chose not to take steps to better the situation, you are not the fittest. That's quite clearly what OP is saying. If you have a mental weakness and some random person on the internet telling you to kill yourself ACTUALLY makes you do it, then why not mute everyone? You cannot control what they say, so it's only obvious to take steps to do what YOU can. If you do not, and you end up killing yourself, that's natural selection. Those with mental weaknesses that seek help and mute until their emotional state is better, are more fit than those who sit in a corner and cry. Natural selection. OP never hinted that people with weak minds should be murdered. So your comparison that people with glasses should be killed is completely irrelevant. Stupid even. If you want to compare with people with glasses, a better comparison would be something like, "It's someone's own fault if they need glasses and don't get them and decide to drive a car and crash into a pole and die." Because that is true. Just as playing a game known for it's shitty community and not muting players the person's fault.
People have rage issues, no? Is that not a mental issue just the same as depression, just on the opposite spectrum? So you're going to run into people that are going to be dicks. You are never going to be able to avoid that. If you don't use the tools given to you to avoid such things while in an unstable environment, then you only have yourself to blame to be honest. Killing people is bad, right? People obviously shouldn't do it. Yet if I walked around downtown Youngstown wearing a KKK outfit, you best believe I'm going to get shot. While that person shouldn't shoot me, it's still my fault for being a dumbass about it.
For someone claiming to be in the area of science, you surely don't seem like it.
