i think it's more social influences than being born that way
most of us are born a blank slate i believe... sure, some people are born with certain biases i guess, but peer pressure and the cult mentality has much more to do with it imo
i have one sibling, a brother, who is the total opposite of myself... he is a born-again bible thumper and actually a glenn beck fan, omg... when he comes to visit he can't even stand to go to a restaurant that has a bar in it, such a prude, how boring... we are total opposite, and the only way to explain it is the crowd he hangs with
my relatives from tennessee are all pretty much bible thumping racists... i went to a family reunion a few years back and i told my mother i wouldn't be coming back for another family reunion outing... too many 'nigger' and 'towel head' jokes... fuck those imbeciles... now i don't include my mom with her redneck relatives, i go to visit her but not those assholes... i hardly ever get involved in politics in real life because it's pointless,, i guess that's why i prefer to do it online where it doesn't matter if i piss people off, lol
