Yeah! I hate misanthropes! I wish they would all just die! Or just leave the rest of us alone! Can't all us happy people get together and throw them out?!? This world would be much more pleasant then!
Hate doesn't solve anything. If someone's a misanthrope, they probably have a reason for it, hopefully, in time, they'll outgrow it. Sure, people dissing our relationships, our happiness all the time can be annoying, but the opposite is also true. All the constant talk of happy, fluffy feelings, or love woes are probably pretty annoying, and sad too.
If you're not a misanthrope, you love people, you're (hopefully) happy, can't you extend some of that love and understanding to them too? They'll probably resent you for it, but they'll resent you anyway, and you don't need that hate in your life.
