Just want to point out, it’s polarising because it’s a wedge issues that divides voting blocks neatly, and nothing to do with it being The Issue that it is.

More people die from obesity, cars, flu, preventable illness, etc. But we discuss endless this one issue… it’s for political science reasons not humanity/moral/etc reasons.

It's different from those other cases because it's like getting in a car accident and other people saying you can't get treatment because it's against their religious values, or saying you're not allowed to lose weight because they don't like it.
