the legal argument goes that “homosexual behavior” is an immutable trait like skin color or gender therefore entitled to the identical protection as such. IOW since two homosexuals can produce children like a white male and black female therefore they should have the same treatment.
It is no different than the USSC outlawing gravity.
That's a nonsense argument. The DESIRE to do the behavior may be immutable.
But there are sober alcoholics. There are 300+ pound people who can slim down and stay there.
No behavior is a "trait".
