Is it moral to use tax payer dollars to fund things that a large group of people in a society feel are totally immoral or unethical? Stated another way, is it ok to force people to pay for something they think is immoral, or should we have a broad moral consensus on something before we spend public money on it.

Examples:
On the right:
Government funding for embryonic stem cell research.
Government funding for abortions.
Certain tax benefits for homosexual life partners.
NEA funding of offensive artwork.

On the left:
The Iraq war.
Government vouchers for private religious schools.
Government funding for faith based charities.
Tax credits for large SUVs.
