Earlier quoted context omitted.
I agree, but anecdotally, as someone who spends a lot of face-to-face time around people on both sides of the typical left-right division, neither of which represent my views, it is very frustrating for me, and I suspect rather pointless for them. I've never left a political conversation like this feeling like I made a dent in anyone's ideology; they just leave thinking I'm a weirdo.
I think the same, and I'd go a step further. I don't particularly _want_ to get along with people who have no problem with abortion, nor with people who have no problem with torture. Why should I see being de-polarizing as something desirable? (And where can I move to?)
(disclosure: I'd ban torture, but for both abortion and most drugs I'd legalise them and try via other methods to reduce the amount that actually occured e.g. better sex-ed and provision of contraception, or better addiction treatment and channeling people towards less harmful (though still currently illegal) drugs.
