That’s a clever line of attack, but having an opinion does not constitute a conflict of interest. Otherwise there would be a whole shit-ton of recusal happening every day.
A conflict of interest usually involves some form of monetary compensation or other fiscal benefit.
I’m discussing the specific choice of what rhetoric they decide to use, not why they are using it. Why they are using it is fairly obvious at this point.
There are many different lines, arguments, whatever that could be employed, though. By paying attention to which ones are specifically chosen, you can learn more about their target audience, which is larger than simply fans of a white, ultra-nationalist ethno-state. Hence their need to continue to use rationalizations like this, instead of being forthright about their intentions.
This one in particular surprised me, as I didn’t foresee it. They’re usually more predictable than that.
