neither homosexuality nor abortion are government-funded programs, so no problem then?
Homosexuality: There are two flaws in that arguement: Hate crimes laws and gay marriage.
Being homosexual is a protected legal status, and that status costs us money to promote and defend. The courts aren't run as a charity; they cost real money. The more laws we pass that codify homosexuality as accepted behaviour, the more money we have to spend to support it.
I personally don't have any problems with people being gay. Everyone should have their own fun. I just don't want to subsidize it. I don't ask the government for discounts on porn or for free beer, and I don't think homosexual couples should ask the government for marriage licenses.
You choose the lifestyle, you pay your own way. Sound fair?
Abortion: I'm sure that taxpayer money can or has been used to fund abortions. I'm even more sure that if Democrats have their way, taxpayer money would be used to fund abortions at every turn. I don't have any references on me, but I'm sure our fellow FReepers have more than enough, if you are interested. I do think that if we care more about endangered species of animals than we do human life, we're a pretty sorry society.
At any rate, I really don't care what people do or think until they start hitting me up for money. Being free to be stupid or wrong doesn't mean that being stupid or wrong should be free.
