Going back to the closet would should be their safest place and only protection. Your concept of protectionism like they are an endagered species is direct from Fantasy Island.
Leeches? Dead-beats? Get back to me when you're paying $60,000 in taxes like one homosexual couple with with I am familiar. It's widely regarded that homosexuals have a disproportionately high level of income, and therefore tax burden. While we're at it, as my brother & his wife are a (naturally) childless couple (due to opposite-sex sexual abuse she suffered as a toddler), I guess they contribute just as much "nothing" as a homosexual couple in your mind. Your argument smacks of the hollow words of hate-justifying rationalization for denying the same rights and freedoms to fellow Americans that you or I enjoy. Surely you can do better?
It seems to me, in the secular world of America as a political and social entity where we hold that none are "more equal than others", we should be encouraging homosexuals to court & couple for life, to remain virgins well into adulthood, to act responsibly and, as a sub-culture, denounce anonymous sexual encounters in public places as well as drug use. These are the same HEALTHFUL benefits that are being quickly abandoned by succeeding generations of heterosexuals thanks to so-called feminist indoctrination. The more homosexuals are marginalized, the less mainstream, less responsible their sexual mores will be. This behavioral reaction is true of any group which is "oppressed" or cast aside by the majority. Part of this marginalization comes in the acts of "conservatives" who refuse to acknowledge that public education, by definition, must be inclusive of the homosexual students as well as heterosexual ones.
There's no reason a sexuality-neutral "sex ed" program can't be taught. However, at this point, students themselves, as the culture teaches them, see their sexuality and the responsibilities, needs, etc. in taking charge of that aspect of living as being unique, different from peers if they're homosexual vs. heterosexual. It's laughable to suggest oral sex, for example, is the domain of homosexuals alone. From that study showing an alarming frequency of oral sex among middle school students to Lewinsky to "virgins" who claim to be such because they've never had genital-genital contact...
A school's roll is to educate by imparting facts (e.g. risk factors, biological realities, etc.), offering opportunities to dialog and to encourage development of self-control and self-discipline. Moral and spiritual education is the first the domain of the family. I often wonder where "true conservatives" send their homosexual sons and daughters or do such sons and daughters "cease to exist" because of what God has challenged them somewhat differently in their lives?
It might be wonderful if everyone grew into adulthood with a heterosexual orientation, but that's simply not reality. It hasn't been reality for millennia, if ever. I believe homosexuals *can* control their actions and *act* as heterosexuals (that is, copulate with an opposite-sex partner) but you can play a doctor on TV, that doesn't mean you'd be worth having in an O.R. I can't begin to guess if one can truly love a spouse if that spouse isn't reflective of one's orientation.
