When it comes down to facts that can be shown, sure.
When it comes down to opinion, nah. People will find whatever reason to justify their already pre-established conclusions.
Unsupported opinions rarely change minds anyway.
But there's still opportunity for interesting conversation by discussing values
& goals which lead to the opinions. I recall a fellow engineer, a Bible thump'n
fundie, who opposed abortion, but was conflicted because reading Ayn Rand
led him to also value rights of the individual. He reasoned that a mother
shouldn't be forced to carry & deliver another human being (the fetus) against
her will. To hold opposing beliefs, & to explore them civilly & objectively
bespeaks rare mental prowess.
Btw, I've seen regular fulminating attacks on Rand here (all that damn
individualism), but I've also seen her works induce tolerance & secularism
in people IRL.
