Personally, I don't think you, or anyone, should. I don't want to either. Unfortunately, we live in a psuedo-collectivist society where our congresscreeps have passed laws forcing us to pay for other people's mistakes.
Now, you've voiced your opposition to homosexuals on those grounds... address my question from earlier. Being consistent - I know how you hate moral relativism - do you also hope to outlaw mountain climbing, skateboarding, smoking, drinking, and driving? All of those things can lead to injury and society has to pay the costs.
Address why I should sit idly by while the public schools, with my tax dollars, attempt to inculcate my children, and the children in my community, with beliefs that offend and disgust me.
If it concerns you, you shouldn't sit idly by. Have you campaigned for the school board?
ROFL...I've done more than my fair share, yes.
