i thought the minor discomfort being referred to was that of changing your name and reissuing a new ID card. i can definitely understand how it would get grating to explain the change at every security check
You should read more carefully. GP wrote "minor psychological discomfort". They're definitely trying to downplay the danger that transgender people sometimes get put in.
Not parent, but I agree with the general point. Leaving this specific example aside which is a real world interaction, we (America) have gone to far to redefine what "safety" is. Ben Shapiro speaking at your school is not "putting you in danger".
