Would you support a comprehensive healthcare opt-out, where an unvaccinated person would forego right to treatment, and also not have to pay taxes for public healthcare?

No, because at the end of the day, we're not going to literally let them die on the sidewalk outside the hospital just because they can't pay.

That means that somebody has to pay for them. Given that unavoidable but inconvenient fact, basic health care and life support might as well be organized under the auspices of the state and the costs shared among all residents.

If you aren't willing to do your part to protect yourself and your community, why should your community protect you, when doing so would endanger others' lives?

The same can be said if many STDs though, drug use, and obesity.

That reflects a deep socialist mentality.
