Agreed, but this cuts both ways. Intent has a lot of moral judgement attached to it - if we're redefining a word to be primarily about outcomes instead of intent, we should also drop the implied moral assertions around it.
Mmm, I'm not so sure. Certainly the things it means about the person responsible for the decision are a little different - lots of people accidentally put policies into place that harm minority groups, etc. But if the outcome is the same and a person in power chooses not to fix it, it really doesn't matter what their intent is, it's a moral failure not to help the people who need your help if you're able to do so. I don't really care whether they say slurs in their spare time with friends, I just want my elected (and un-elected) representatives to do what they can to prevent people from dying of starvation or preventable diseases.
