I think in this case, y’all is more accurate. At least to my understanding. “All y’all” is for every single person in a group, based on my understanding. “Y’all” is the group as a whole. As someone who voted against Trump twice, I’m fine being lumped in with my stupid brethren. We deserve it. But I really don’t want to be seen as one member of that stupid group or people.

Splitting hairs, I know, but what else would we do in Internet forums!?

Oooh Trump’s gonna get in a fight with Canadian Trump! Get some popcorn y’all!
