As immature as they are, I personally don't see what the fuss is all about. Everyone's sense of humor is different, and I find some of them to be creative and at least give me a chuckle here or there. As to the comparison with racist little kids, etc., I view it differently on the basis that Cockmas is not out to offend any particular person or group. It's just light, immature, and fun. I mean it's a bunch of cocks dressed up in costumes for pete's sake. Most of the people on this site have them, so yea.
In seeing them again this year, I view them now as for better or worse (better imo), a CAG tradition. Nostalgic feelings of seeing the cocks of yesteryear come back, new and old.
But ya, people are entitled to hating dem cocks for one reason or another. I'll be glad to see them for another year.
