encompasses an injurious attitude of dehumanization, of disrespect, that is violence. it's the attitude, not the argument.
Pardon me for inserting myself here, but are you arguing that words aren't violence, but attitudes, i.e. thoughts, are?
Because frankly, that would be even more absurd.
As for the "other kinds of harms and injuries" being "even more hurtful and damaging", I'm going to do as the Aussies and go yeah, nah. To a great extent because I've never managed to kill anyone or put them into hospital by saying bad things, or having injurious or disrespecting attitudes towards them. And that's not for the lack of trying.
