In my experience Boomers are basically all cemented in their position, for example the single most feral leftie I've ever met was an old ass biker boomer who apparently hung out with the black Panthers as a teen and basically wanted to murder ever president since Johnson. Meanwhile I've never met a rightwing boomer who could have their mind changed regardless of whatever logic chain you use, I've had more conductive arguments with neo-nazis since at least they try to argue rather than effectively just going nuh-uh.
