You can’t discriminate because of gender.
You can’t discriminate because of height.
You can’t discriminate religious belief, culture, ethnicity, etc.
But there’s nothing wrong with bullying people who aren’t the image of health, because we all know fat people are unhealthy, and they deserve it, brought it onto themselves. And when they get too skinny, just feed them (but remind them, they can still get fat, because it’s not an eating disorder until you can see it.)
This is progress going backwards.
