A female is strong, suddenly she is a Mary Sue and it’s part of some feminist agenda.
The only reason people think like that is because the constant push for "strong female characters" and they just happen to be mary sues because those people don't understand that a legit "strong" character has both strengths and weaknesses. Also, most of the other types you describe are all slammed by the same people who constantly demand that all females characters must be "strong".
