I have been blocked on a facebook page...?

I was blocked on the facebook page CREATIONISM... debating with someone and I guess he didn't like what I had to say so now I can't respond to anything except on the wall. This is absolutely crazy! If you have this debate forum and it someone doesn't like what you have to say all they have to do is mark you as spam or harrasement! So I did it right back to the guy and try to get him blocked. Anyways, how long will this last, and who thinks this is absolutely CRAZY! I wasn't even spamming let alone being rude, mean, or anything for that matter, just absolutely crazy...
