With all due respect, if it is the post I think it is, then you may be overreacting a lot. People can have an opinion on who should be able to vote and who shouldn't. Their opinion doesn't matter because we have the Constitution and the Law. We joke about stuff like that all the time. The poster in question may not be joking, but he is entitled to his opinion and be countered as part of the discussion. IMO, he was making a larger point that the many people ignorantly say one thing and then vote for literally the exact opposite, and often are extremely destructive to traditional American values. Maybe those people shouldn't be granted the responsibility of voting? I'm not stating an opinion either way, just showing arguments can be made, and it literally doesn't matter ... it doesn't change the Law and the Constitution.
If that isn't the post, then my apologies.
EDIT: regardless, I don't think mods should be positing in threads where they ban others for posting opinions. I'm not trying to be a d*** ... just stating my opinion. My 2 cents.
