I've never seen "outrage" about it, mostly annoyance and eye rolling. It's douchey at best. It's usually the least respectful people (primarily men/teenage boys, but not exclusively), usually using the term in a derogatory or dismissive way against women, and often dehumanizing or objectifying them. It's also similar to referring to black people as "blacks". It's just reductive, like that's the defining feature of them. That may not be fair. May not be how you use it. But that is the connotation of using the term in that way.
