My brother sent this article. It's cute. I like lawmakers with a sense of humor. But the edge, the stereotype, is still there. Republicans are the enemies of gay people.
It would have been funnier if the lawmaker had targetted his own party. The same point would have been made, with perhaps even more bite. Republicans really don't like anyone who isn't completely in line with them. They hate all of us.
It would also have been funnier if he had proposed that heterosexuals not be allowed to adopt. He could have gone on to point out that most crime is committed by heterosexuals, most child abuse, etc.
So I guess he isn't funny at all. When you recognize that he could have made the same point with real humor, the gesture becomes revealed for what it really is: bitter, childish, bigotry.
