Number 1, the issue of health mandates has already been decided by the Supreme Court. In 1904. Jacobson vs. Massachusetts. Individual liberty is not absolute and ends where the life of another may be threatened. Get over it.

Number 2. Public health dissemination of information is NOT coercion or force. It's an education campaign.

Number 3. There's a huge step between not caring if someone lives or dies when they are acting recklessly and actively wishing them dead. Don't pretend like it's the same. It's not.
Letting them take their chances completely is simply honoring their request and the boundaries they set.

Number 4. Assuming that there have been actual death threats against antivaxxers , don't act like that's a one sided thing when Fauci had to hire a security detail because his family was threatened. And many many other liberals from all walks of life have gotten death threats too. Two wrongs don't make a right, but don't act like conservatives and antivaxxers are innocent here. They're not.
