I am not slow about blocking/banning Facebook users from my Facebook pages.
If a person wants to spread hatred of homosexuals or foreigners or persons wanting to change their gender or persons of a different colour or race they can spread their hatred on Facebook, and elsewhere online.
There is plenty of room and scope for them.
But they won’t do it on any of my Facebook pages. I will block them.
In the overall context of the capacity and venues to spread hate my individual action is of limited value.
Nevertheless, culture changes by each of us doing what we can to change the world.
