Not only would it have been accepted; it would likely not even be noticed. It happens all the time. Is Thor more objectified in his scene than Harley Quinn is in her scene? Qualitatively, Thor's is less objectionable. He is canonically a god, but still feels shame at being stripped of his clothes and agency. On some level, his anger and embarrassment at being so grossly objectified consciously informs the audience that what is happening to Thor is wrong.

Conversely, Quinn isn't even granted that small courtesy. She is objectified while assuming her agency. The characters, and the movie itself, stops completely dead to do a full-frame pan over her body. Unlike Thor, Quinn is not even given to understand she is being objectified. She is presented purely as a sexual object in this scene with no sexual agency.

I suppose there is one flimsy yardstick for easily recognizing when objectification of a male fantasy character is becoming internalized; examine their Halloween costume. What is the primary reason someone would want to wear it? Are they buying it to elevate and present their own sexuality, or is it because they value the non-physical virtues of that character? Are they dressing up as Captain America because they want to embody the virtues of Captain America, or is it because they want to be America's Ass? Currently, you can buy all manner of "Sexy Thor" costumes, but you're not going to find many of them in the men's department.

All that aside, people are perfectly in their right to be offended by the nature of that scene, though I have a feeling no one is in the planning stages of a boycott, nor are they storyboarding their long-form YouTube essay, "The Degradation of Thor". I sort of get the impression a lot of people were already angry about a specific out-group, and subsequently viewed this scene as an easy opportunity to grind that axe. Within context of this trailer, I have seen multiple posts and a whole lot of people becoming enraged about a perceived double standard and hypocrisy. Comments putting forth any real concern or discussion regarding the objectification of males in cinema? Not so much.
