So, let's look at cholera for example.

If I simply quarantine and or shoot everyone infected with cholera, will that "solve" the cholera problem?

Uh, no.

What we should do is treat (help, not ostracize or demonize) those "infected" with hate (by teaching them logic) and prevent others from becoming "infected" with hate (by teaching them logic) and cut off the source of the "infection" by "cleaning" the drinking water (official public discourse).

Fighting hate with anti-hate is a fools-errand.
