What would that prove...that they "feel" better about themselves today than in 1950? They're still gay...whether you believe that behavior to be aberrant or not, no one likes it shoved down their throat or that of their children. I think people are very tolerant to other people's behaviors as long as they don't impact on them personally. Keep it out of the schools and the constant barrage on television, and there would be much less furor.
The same held true for "gay marriage"...which by definition, is an oxymoron. They could have had civil unions..which they refused, though that entailed the same benefits of marriage...the reason being, that they must be "equal"..it just doesn't flush. And if you don't believe that we're on a slippery slope, you better look into NAMBLA and their efforts.
