Come on you're being a bit disingenuous. They don't respond to lesbian's requests either but they don't show up when Bindel speaks, nor at WPUK events.
And I can evidence this yes, go on Richard Spencer's Twitter timeline, at just after the time the Charlottesville event went down and you will see how he tells his followers not to support him.
David Duke did the same thing, calling Trump a sellout the first time Trump weakly denounced Nazis, only he (Duke) began distancing himself on social media months earlier, when he realised that while Trump may be a shit, overblown blaggard, he wasn't quite going to deliver the Aryan Republic of Duke's dreams.
Remember all the hail trumping that Spencer was doing? Well that swiftly stopped after Trump denounced and Spencer claimed he was going to vote for Biden instead - because apparently, he (Spencer) is an accelerationist, who thinks Trump will pacify people into thinking things are being tackled while actually empowering the people Spencer hates, while Biden will provoke the "solution" faster.
It works. I think she needs to denounce, I won't be changing my mind. But what does that matter? KJK will obviously do as she pleases and you are more than welcome to your own beliefs.
