I've rarely seen those Nami fans talk about Nami herself. Coincidentally, 99% of them just wank Zoro and Nami. Even though Luffy is part of rdt, I never see those fans prop him up. As a neutral, it's gonna be hard to convince me normal fans support RDT when majority of that fanbase's topic is shitting on Sanji.
And the Nami hate is BECAUSE of these RDT fans. Lol. I've rarely seen Nami fans who aren't part of "RDT" argue with Sanji fans. It's clear who the aggressor is if you're neutral
