Mankind needs to learn to be more accepting

Sure, I’m guilty of judging people, as is almost everyone, but I don’t know why people have to be so mean to others. Why would someone ever want to put another person down for what they do in their personal life? Unless it’s directly affecting you, keep your mouth shut. Weather someone’s being judged for what they wear, what they look like, if they have a disorder, whatever it is, it seems like people are always so quick to say nasty things, and right to the persons face! I just don’t get why if people have hurtful things to say they can’t just keep them to themselves or hey, maybe even find something better to do with their time?
