It's silly to say Elon is nuts. He has an agenda and has the means and expertise to meddle fiercely in European state affairs. He's doing so already and supporting right wing politics across Europe. It's typical Mumsnet ignorance to lament how crazy and loony people like Farage, Trump Elon are. They're not crazy, they're strategic and very popular.
One good thing to come from the spotlight on gangs systemically and brutally abusing children, is that it's now a lead story on BBC News. That's the BBC we're talking about...
https://www.bbc.co.uk/news
Allowing people to talk openly about immigration and airing concerns has become quiet impossible as there is an understandable fear of people rioting about these sort of issues as we have seen in the summer, which is a danger to peace in our country.
The sad, sad truth is that our politicians are and have been extremely weak and driven by self interest. There are no competent politicians and Starmer is the absolute opposite of a leader. In regards to men with Pakistani heritage or nationality systemically abusing children in the UK and local authorities turning a blind eye, that's simply despicable 
. It's not an issue of race per se though, rather it's that certain groups of men are protected by society. In this case it's men from minority backgrounds (and often Labour voters / councillors); previously it was church leaders or popular BBC celebrities such as Jimmy Saville. The problem is that some groups of men are untouchable and girls (sometimes boys too) are accepted as collateral damage by our politicians. Elon is simply tapping into the understandable anger about this as most of the abuse scandals are swept under the carpet. It's a simple and effective political strategy, not mental illness.
Of course Elon has no interest in protecting children's or women's rights, so much is obvious. There is a drive to right leaning politics and we are seeing some 'strong leader' politics emerging in the US and Europe, supported by Elon and others. It will be interesting where this takes us or if it's all just a whole lot of hot air covering up the fact that the rich are getting richer and the poor poorer. The more inequality in society, the more danger to women and children.
Of course it's true that the population in the US and Europe has seismically changed since the post war period. It's up to each individual whether they believe that's positive or negative. What we should expect rom our politicians is integrity and leadership, sadly we are not getting that and Elon is simply exploiting a power vacuum.
