I guess I just don’t understand why seeing people make different choices than you is undesirable to you. Moreover, I specifically don’t understand how it doesn’t make sense to you that people want to dress as comfortably as they can for what is likely one of the least comfortable common situation to be in.

Not the parent, but I feel the same way so I'll chime in. It's basically just something that stands out and looks "off" so it's (very, very slightly) uncomfortable. I'm not going to do or say anything differently, it's just something my brain processes as weird. I feel the same way seeing people dressed that way anytime they're out in public, not just for air travel.
