As others have said, she needs to specifically denounce them but clearly she's not going to or would have done so by now, so I'm guessing she's enjoying all the speculation and controversy. Also equally obvious is that there are many clearly not horrified by this, who want to dismiss those with genuine concerns as either being TRAs or snowflakes.
I've seen far too many on here willing to dismiss the obvious danger in not vehemently and specifically telling the Nazis they are not welcome, which is easily done if you're not bullheaded, stubborn, or wanting to court controversy regardless of consequence - by the way, that danger won't just be incurred by people who don't have the luxury of existing in a white middle class bubble, it includes the harm that will be done to the gender critical movement and therefore all women. There's another truth here - toxic people tend to create disharmony and division, I'm now thinking that's as true for the TRA misogynists as it is for KJK.
I've overlooked a lot that has made me uncomfortable, including the dismissals of radical feminist women of colour regarding who she was interviewing and being interviewed by, (I mean seriously she shared screen time with a white supremacist and then claims she didn't know, really, in the age of Google?!!!! Yet I admit, I overlooked this, wanting to believe her, as I didn't believe she could condone those gross beliefs and I believed she was effective. However though I am more than sure KJK won't give one f**k that support stops when you refuse to take one simple action that will add much needed clarity to a situation - denounce specifically, tell Nazis they are not welcome at events. And yes, there isn't a doubt, sorry if you are sieg heiling, you are a Nazi and some of these scum are known Nazis.
If you don't do that, I think that means, you either don't think they are scum the way normal people do, or you need them there to create controversy which will divide people and women further and cause more political tribalism.
I mean, the mocking of people with genuine concerns over this, the scornful dismissal about people who obviously aren't TRAs, who are gender critical themselves on here has become so bad that I am genuinely wondering if the far right infiltrated Mumsnet now? You're not a bunch of 4chan trolls triggering "snowflakes" but that is what this is coming across as - you do know there is precedent in not denouncing Nazis in the strongest terms don't you? Or do the potential consequences of that just not affect you?
