"Still getting off far too lightly given the damage they do IMHO."
If moral universalists damage someone, absent extraordinary conditions, they deserved to get damaged by moral universalists. Secure your shit.
As with all criminals, they do the most damage to themselves. You may be involuntarily exposed to moral universalists, but take a moment to pity the universalist: they have to live with one literally 100% of the time. That's really gotta sting. (As shown upthread.)
