Elena Kagan not gay says White House, but is there something wrong with it if she is?

The headline:

“White House complains about CBS News [Washington Post] blog post saying that possible Supreme Court nominee is gay.”

So, my question is, what is wrong with being gay?  Does the White House have a problem if she is gay?  Is there anyone except the White House who cares?
