Again, you're attempting to project your emotions regarding it, onto others.
I know plenty of committed gay couples. Great marriages. Wonderful families. One angry person on the internet does not a reality make. The real world holds much more truth than your words.
Statistics will show you most mature committed homosexuals live solitary lives. Even those who manage a mutual living relationship of year or two is miniscule.. and amounts to little more than sharing rent. The few who manage long term co-habitation are ones of exhausted, hollowed out convenience.
They are a parody of real marriage.. but they find some solace in pandering the media's thirst to find 'happy homosexual' couples to put of real estate and reality shows... or news soundbites.
