A somewhat common phrase within kink is “Topping from the Bottom” which is also presented as being a bad thing.

I do agree that it is, if not consensual – and can be bad for both the Dominant and the sub in scenes.
However, I also feel that it’s a term that gets misused. It can leave subs afraid to speak up or communicate. It can also send the Dominants on the wrong path. But, worse, it can be used as a tool to get away with abuse.
