It's not the best analogy, sure. Your reaction is worse though. It's like reacting to someone who takes offence at hearing about a knife attack by saying "stop being so upset about other people's internal organs, it is fucking creepy".

it left me wondering about the kind of friends who would feel comfortable coming in with you to use the urinal while you're taking a shit.

And then stay for the duration of your shit because they can't leave without leaving the door unlocked.

Sure, go for it.

Uhh I'll have two with points and a big flat one
