I'm accustomed to nobody wanting to discuss this sort of thing, but I'll never be okay with it.
If you don't understand why somebody you disagree with — even disagree with fanatically — feels how they do, then you cannot have productive debate. If you're unwilling to try to understand why, then you don't have any high ground, you just have a difference of opinion.
An easy practice to engage in? No. Important? Yeah.
