There are some people who just do not like gay people. This is a fact of life. And it won't be argued or social engineered out of them.
Likewise, there are many communities around the country where gay people are not welcomed. Again, another fact of life.
Which is why I prefer to mock bigots rather than argue with them.
I may not be able to change their minds, but hopefully they can amuse me before I grow tired of them.
