You need to look up what the word “nominally” means, it completely changes the meaning of the sentence you’re objecting to.

I’m not a lawyer, but my understanding is that US law doesn’t typically operate on technicalities like this. Would the “reasonable man” believe the bumper sticker was an offer to any passers-by to search the car and take any guns they find? I’ll answer my own question — definitely not.

I’ve been making a similar point for years now — I don’t need any help generating bullshit, I’m already very good at it.
