They're not wrong that it is rooted in misogyny, considering that you don't really use 'whore' or 'ho' with positive connotations. Not to mention that terms like thot are more likely to be found in incel communities these days, which is hardly a glowing endorsement of the term being used with good intentions.
As someone else said, at least 'thirst trap' doesn't lay it squarely at the feet of women, as if men aren't capable of doing the same.
