Pedantry over trivial side issues serves to distract from the primary issue at hand, which, as another commented, doesn't make your priorities look so hot.
According to Wikipedia: "Harassment can include "sexual harassment" or unwelcome sexual advances, requests for sexual favors, and other verbal or physical harassment of a sexual nature." and "It includes a range of actions from mild transgressions to sexual abuse or sexual assault."
I referred to a "stressful situation" in justifying the PT(S)D claim, i.e. to say that this was indeed stressful (as I explicitly say), whereas you seem to be in the impression that I said it to downplay the incident.
Until a few decades ago, homosexuality was a disease that was OK to be cured with things like electroshock treatment. Heck, people had lobotomies inflicted upon them, in the 20th century, for all kinds of BS reasons. Here on HN too, many will attack the prevalent over-prescription of drugs and diagnoses of ADHD to children.
Words have meanings, just because someone interprets them in their own way, doesn't mean they can claim X when it's not considered warranted.
So regardless of this particular case, we can, and do, society collectively does set the bar for what can be considered X or Y -- and someone can argue based on that.
(That said, grabbing her hand and not letting go despite attempts to free it, and groping her body, clearly fits the bill for sexual harassment and a stressful situation).
