Some advice, eggzbroperson: any kind of rant, no matter how well-intentioned, can end up making you look stupid. Sometimes the best thing to do is just to let things go. If you have a problem with a particular strip, just rate it "bad," maybe leave a comment, and that's that. The best thing that you can expect to happen as a result of a rant is people making fun of you and you learning not to do it anymore.
I think boloboffin was pointing out that some of your own comics could be seen as "mean and offensive." I looked through your other strips, and there seems to be a lot of violence. Some people might be offended by that as much as you are by racism. Personally, I'm a mixed-race, disabled, religious minority pacifist with several GLBT friends and family members, but I'm rarely offended (much) by anything on this site. Not all of it's funny, but I don't let it get to me. Having a sense of humor is the whole reason we're on this site, right?
