You'd think pedants would be better at following/enforcing rules. A lie by omission is still a lie, yes? If this person was for not omitting a true and relevant fact because said fact does not serve your narrative, how can you possibly claim moral superiority? Is that not the same thing as being an accessory to a lie? Personally I agree assault rifles should be banned regardless, and that banning all guns makes more sense than legalizing all guns, I'm just not a fan of sneaky, thumb-on-the-scale bullshit.
