i started typing some mumbo jumbo backed by statistics and evidence trying to prove my views blah blah blah...and then said fuck it. Nones gonna change someones mind especially their beliefs over the internets. So all this is, is trying to prove the other is wrong and a dumass and you're right. Congratulation's, here's a cookie.
Just look at it like balance...you can't have 1 without the other. Done. Move on.
If there was only 1 belief, 1 culture, 1 language etc the world would be a very boring place. There's no Utopia...so stop effin lookin for one.
