Quite correct, but out of these self-destructive behaviors, the only one the government protects and legislates for is homosexuality. Free condoms (that don't prevent HPV, as the doctor said in the above article), hostiles, special rights, etc., all seem like a tacit endorsement of the self destructive behavior (interesting that you fianlly admitted that it is).
Apparently you haven't been paying very close attention to government restrictions on smoking, and government required warning labels on alcohol.
Personally I think that government should stop all social programs, stop all socialized medicine, get the hell out of our lives, and leave us alone unless someone's rights have been violated.
