You were arguing against an argument by popularity or something like that, but giraffe lady didn't say that you should be uncomfortable talking to nazis because they're near universally reviled? But because they are reprehensible, not due to how they're considered.
I think isolating white nationalists just makes them congregate on echo chambers more. There should be a balance; you should not talk to racists/people with evil views if you can't maintain boundaries with them. So I don't disagree that you should be uncomfortable
You didn't say it outright. But your words definitely contained a strong degree of innuendo that two groups were, in terms of potential for being intrinsically repulsive to others -- basically equivalent.
