The guy in the video said they asked for "able-bodied" men. Big difference.
Yeah, if it were "able-bodied" then that would prevent any embarrassment, though you'd get way more people than you need, but the article above says:
Then, a pilot announces: "Ladies and gentlemen, this is the captain speaking. We would like all strong males to the front of the aircraft to handle a problem passenger."
And I get why they would say "strong" rather than "able-bodied" because, again, they probably don't want like 100 people to show up.
