If someone is attracted only to woman with male genitalia is not feticism, nor a “chaser”, it’s a sexual preference and, just like any sexual preference, if it’s carried out in a respectful and non-creepy way, it’s perfectly reasonable and must be respected.

I agree with the proliferiation of labels not being super useful and possibly damaging, while sexuality is very complex. What I don’t agree with is your critique of “liking only genitalia” = “objectivizing”
