...and you're a doctor? ( frankly if you want to HIV and HIv research I would love to have the conversation. However I doubt if it would get too far.....
And you're confusing Nanny State, which is what what you like to call the current gov't, with Big Brother, who came close to being voted in, re: your last line " You know using the same logic and legal precedent the government could be used to ban Gay sex entirely"
as usual your posts make no sense.
The cornerstone of reversal of anti-pornography laws was the right to privacy. So if the argument that the government has a right to regulate what goes into pornography , then it therefore has a right to regulate the whole sexual act.
Regulating sex during a porn shoot and calling it "Commerce" would also allow the government to regulate kissing in movie theaters, and whether you use 2ply or 1 ply toilet paper in the bathroom of a restaurant.
There are far more dangerous acts done and portrayed in TV's and movies than bareback porn. In this case some well meaning but uninformed individuals choose to impose their ideals because they think they are morally right. The reason we have a constitution is to constrain government to the limited area it has power to do so. Because political views and majorities change. The liberal ( not liberatarian ) mind ignores this and is just is for or against a myriad of ideals depending on how they feel on the topic. They do this without thinking about the consequences of laws going one way can be turned in the exact opposite way.
