Fat people have no business voting.
Learn to tackle the small challenge of managing your own weight before thinking you could contribute to managing society in a positive direction. Your own body is literally the one thing you have control over. If you can't take care of it, it speaks volumes.
Everyone is capable of losing weight, so this isn't denying anyone the right to vote. They simply need to demonstrate they are qualified to do so - again, something that anyone can do.
(Inb4 coping and externalizing the blame).
Every polling station should have a pull up bar so that people could practically prove they are capable of taking care of themselves. Perhaps a separate test would be appropriate for women.
Any argument against this will be emotionalist liberal dribble.
