af: " they really don't desire anyone on 'the right' to change precisely because their own identity is so wrapped up in the agonistic relationship with 'the right.'"
that is largely spot on, in my experience.
i also suspect that lack of desire (at least sometimes) comes from an assumption that those on "the other side" simply cannot - or do not want to - change.
i would also point out that in my experience, those on "the right" have a very similar perspective on the whole "changing those who are wrong" thing. they'd (both left and right) like to see folks change; they are sure that if only those other folks could understand the correctness of their own perspective, they'd see the light; then, finally, they give up and fall back on a "they'll never change, they are way too invested in their wrong perspective - fuck em".
i definitely acknowledge that those on the left can seem much more like prostylizers, and they often come off as more self-righteous, imo.
"i've gotten the feeling many leftists have no desire to see people change course in a radically different way"
i would agree with that to the extent that leftists are usually politicians, and politicians are deeply invested in their role - truly radical change would most likely eliminate that role. i'm not sure how different that is on the right.
but then i guess i am diverging from the actual question. maybe a left vs right question would be better suited for what i am getting at.
