They did clearly state "given the context". The context being someone who, supposedly (I don't know, that was before my time and outside of my circles), had those traits.
So I think saying "by thinking anyone with differing opinions is Xist" is a mischaracterization of what was expressed originally.
We're not talking about "anyone with differing opinions", we're talking about a specific person who publicly denounced their coworkers based on their gender and sexuality.
