I don't discriminate. I treat Gooks, Nips, Coons, Hillbillies, Wops, Dagos, Beaners, Spicks, Honkies, Pakis and Sand Niggers equally. Complete and utter disdain for the F###### lot of them. But in all honesty I think many people simply feel more comfortable in the company of people from a similar social background. I think the factors can change and that race, gender, nationality, age, class and sexuality can all be interchangeable. Most people simply feel more comfortable around people they feel they have similarities to.
Maybe society has changed and we have become more selfish and cynical. I remember as a kid going round with my mates and popping in and out of each others houses at will, doors were never locked, the whole way we socialised seemed different then. Western society seems more gaurded these days and not as friendly as it used to be. As I have gotten older I have certainly become more cynical of our western culture. that is one of the reasons I will be moving to Thailand in the future, but thats just my take, does not mean its right for everyone.
