So many hilarious ones via google, both for and against gay marriage. Since we've been talking about the NSA so much..... Ridiculous. I hope I live to see the day people don't care one way or the other about sexual orientation.
I'd be curious to see the "hilarious" ones against marriage equality. I've seen a lot, in person, on line, and all are basically "I think you are icky" or "god thinks you are icky".
Jesus had two dads was the only one I thought was funny. I am pro-gay rights, but I didn't think that was a good or even fair fight. Lots of homophobe signs were really boring. I came across a better example and I'll dig it up in a few minutes.
Some of the hiliarious ones are of the "I can't believe people actually believe that" ilk. Kinda like the pic I already posted.
