It was a mildly inappropriate thing to do. Baby looked a bit disconcerted. Disapproving even. We don't know what this guy will be like as a parent, but his kid has (AFAIK) a healthy, solvent father who really wanted him. Which is more than many kids have.
Perez Hilton has a persona that some people are able use against him as an excuse for what is really prejudice against all gay parents.
I have no prejudice against gay parents, I am just opposed to people - all people - buying babies. Some people suffer from extreme paranoia when an opinion they dont like is put forward. Tough.
