I think this (the whole okay hand signal accusation) is clearly nonsense but regarding the continual Nazi smears, I think KJK should just make it really, really clear they are not bloody welcome. They do tend not to turn up when that message is sent loud and clear - of course not always, if they want to have a ruck with antifa but much more likely not to bother if she has basically told 'em direct, don't bother coming.
No, she isn't responsible for them turning up, no she didn't create them and no she shouldn't have to but there it is. I know she has denounced Nazis previously but has she expressely said don't bother coming, I don't need or want your support? If not, I think that yes, she should say this or something similar to this, while I do agree you need to work with people from all sides - there is also a limit, you wouldn't (or shouldn't) bloody work with Nazis, the Taliban etc...
Maybe make a statement in one of her videos before a planned tour saying no Nazis need bother or something? Just a suggestion, they don't turn up anywhere (other women's groups/ events about this issue), and yeah those people are nowhere near as effective but these accusations are seriously getting out of hand and need to be nipped in the bud.
Which can happen if she does denounce more specifically in a way that sends the message "don't bother turning up". Honestly, if she doesn't want to do this, then her choice but yeah, that does get me wondering. Not that she's a Nazi but that she's purposely courting controversy with no thought to the consequences. That's dangerous and really won't help the issue or the situation. Or KJK.
