Yeah, you are right on that ideas making an action immoral do not make too much sense. What I'm trying to say that the idea behind those actions is immoral, making the action immoral. But still, I'm not sure about that.

I am sure about your second part. If you make decisions on predicted consumer behaviour, most of the time you are OK. The same happens when you are testing an hypothesis or something like that. What makes it immoral is propagating the stereotypes and probably worsening discrimination. So, it isn't a problem if you assume all men want to clean their hair or don't want to have dandruff. It's not OK if you assume all men don't know how to cook, even if it has been predicted (or demonstrated) by consumer behaviour.

It's not that these actions are always bad, is that they are bad in the current society we live in.
