Multiple employees beat up a gay man after he had some PDA with his partner. No matter how you look at it the optics are horrible. Short of Mr. Dingus having a weapon or shouting slurs or something like that: there’s no justification for the employees to beat and attack him.
I feel like you’re jumping through several hoops to put the blame back on the person who was beaten by multiple people.
If you’re looking for a technical term, you would fall under gynosexual. But even with the term: only you can truly define your own sexuality.
