So it's not free.
And I shouldn't have to pay for the sexual habits of my neighbors
And you shouldn't have to pay for what else...entitlements, prisons, school taxes etc...right? I'm guessing you'll say no. Which is fine but the current system we have--until it's changed into a pure libertarian system where you're on your own consequences be damned...you're paying for all sorts of crapolla that you had nothing to do with. If your neighbor does blow, gets arrested and is locked up in Joplin...well thats something you're paying for; about $30K a year. Paying a few pennies (300M dollars according to Romney--$1 of your tax money) is a bargain.
I see your point though. It would be much better if people just stopped having sex. But that doesn't seem to be on the horizon.
The best idea of all, cut taxes to allow a single income house hold and allow a parent to stay home to make sure that the kids aren't promiscuous. But we like our bombers, tanks, parks, Air Force 1 and it's ridiculous expenditure, having mail delivered on Saturdays, etc...
