Within weeks she knew he was the one. Shared political beliefs "are one more set of criteria that lets you know you're soul mates," she says. I read another thread like this. Basically leftists want to enforce leftist ideologies on others and demand that leftist othodoxy be enforced in a relationship. Its selfish to demand ideological purity in a relationship, but is'nt this typical of liberals? You see the same thing in colleges where professors demand their students parrot their liberal ideas back to them for good grades and failure to do so results in punishment.
Well among the politically correct, if you believe in conservation of forests, you must also stand against SUVs and for animal rights (and don't look down on those who spike trees). If you are "for" animal rights, you really should be a vegan "and besides, it's healthier". And when you go to the rally to protest Starbucks not using the "right" organic coffee (possibly one that exploits the harvesters, not with deadly toxins but really lousy benefits packages) you'd better not make moral statements about the nice homosexual couple raising their adopted children, if you do you are a racist/sexist/homophobe.
It is a unifying ideology and you'd better get in lock step with political correctness if you are going to try to land one of the advocates.
