Of course they are. I personally only feel that the only tragedy to an antivaxxer getting run down in a parking lot would be if the driver didn’t immediately shift into reverse and repeat the process.
However, the ultimate price we pay to shut these idiots up is too high. If we continue to adress them with the scorn and lack of respect they deserve, they tend to go away on their own.
If it was just the antivaxxers, I’d be glad to let them die, but those kids don’t deserve to pay for the fact that their parents are morons.
