I know much of what is deemed abuse these days would not have met that definition forty years ago
My sense is that it's not so much that the definition that has changed but the norm in how to deal with these situations. In the past, teammates made a funny nickname to bring up the issue. Today, we've created a culture where people feel more comfortable taking more appropriate action.
Pro tip: leaving out political figures in your commenting is always the right choice, regardless of your affiliation (I'm not the downvotes, either).
