Similarly, as much as anyone hates antisemitic speech, it IS protected speech because it’s free speech.
At some point we are going to have to decide in this country if we wish to continue forward with the enlightenment and grow up as a society where we actually talk to eachother again, or are we going to descend back into declaring someone a heretic and burning them, or in modern parlance, deplatforming and doxing.
You don’t stop ignorance by banning it or doing virtual book burnings, you stop it by educating people with the ignorant viewpoint.
Banning speech and ideas simply grows it underground, where you never get to witness it through glad handing, but you will experience it at the worst possible outcome instead.
