"old, victorian morality laws"
Laws such as contributing to the delinquency of a minor, public indency and public sex, sodomy, etc.
All those things should be legal, then, according to you. You must like Gay Pride parades, then, since that's all those things and more rolled into one event.
I am no fan of parades, but they are protected under our first amendment as free speech and free assembly
and laws about juvenile delinquency, public indecency and sex in public are completely irrelevant to this discussion
sodomy laws are a place that the government has no right to go. that is my belief
