It's nothing personal that I ignore all "friend" requests, it's just that I don't know you and therefore would be lying if I called you all friends. I guess you could invite me out for some beef chow mein and a pina colada, but if you were REALLY my friend, you'd know I don't eat meat or drink alcoholic beverages!
Also, I've converted to dognosticism. I don't have or need a dog, but I don't deny your right to a personal dog. I also don't mind hearing stories about your dog as long as you don't try to get me to accept your dog and renounce my doglessness. It doesn't mean I'm a kitten worshipper, although I don't have a problem with kittenists. I just think people are entitled to their vices.
Except smokers. :P
