This is one of the main hurdles I'm seeing. The prejudice people that could have their minds changed by forming relationships and being educated are just being shouted at, insulted, and attacked. It's only going to make them dig their heels in and fuel their hatred for those groups. It's also going to drive them underground and then we'll have secret racists/homophobes/whatever that will be prejudice in ways that are harder to overcome. Things like systematic racism or passing bills that don't allow certain groups to do certain things, indirectly.

People see those prejudice people getting 'cancelled' and think that's going to stop prejudice, but it's just making it worse.
