Good for him
It's not like gay people have a choice about being gay or not. And they shouldn't be treated as second class citizens. The more high profile individuals come out as gay, the more people will see that it's no big deal.
The religious right needs to get some backbone and tell their flocks in no uncertain terms to quit stigmatizing gay people. When Jesus said "love thy neighbor", he didn't say "and treat the gays and minorities like second class citizens". A little positive leadership would go a long way, but that doesn't seem to be written large enough in the Bible for these clowns.
