Indeed, but should we at least establish an unbiased study of those members of society that've opted to brutally deprive themselves of an ear for love, and the subsequent (and long term) effects said act had on their lives and those of their offspring? Should we instead, simply assert that such are completely "healthy" individuals? All that said for humor, but seriously; one simply can't make grandiose assumptions for society without a whole-hell-uv-a-lot of observed data to begin with, and we've precious little, if really any to go on, regarding the gay marriage issue.
The ONE thing that's universally understood in ANY "study" is that the children in any such unions DO suffer social stigma....So how's this really such great idea where children are concerned?
Nowhere within my personal ethics and beliefs can I find ANY excuse for essentially abusing helpless kids for ANYONE'S selfish reasons...but then, I'm not a "liberal".....
