pointing out that they're afraid of other peoples' genitals is better because (1) it's true (2) they are *specifically* weak, mentally, to having their "toughness" attacked (3) it invites normies to de-identify with them e.g. "I don't want to be a scaredycat so I will not freak out about bathrooms"

Side note off of #2: accusations of hypocrisy never land on the right because they the right doesn't value honesty like that. What DO they value? Strength. Call them weak, it hits; gets under their skin the way "hypocrite" works on the left. Instantly they MUST prove they aren't. Drives em mad.
