https://www.fiightback.co.uk/ https://twitter.com/user/status/1089857230839693313 Only seen this organisation on Twitter so don't know anything more about them but it certainly shows that concerns exist about FII outside our community.
@Tilly has links with this I think. It seems good based on posts from Parents of ME closed FB group I am on.
Parents trying to get an autism diagnosis for their child are vulnerable to being accused of FII. Parents who have undiagnosed autism are even more at risk of being accused of this. Even mothers with a clinical diagnosis are at risk of being accused of 'encouraging autistic behaviour' in their children! The parallels with what has happened to parents of children with (especially severe) ME are quite revealing. https://axia-asd.co.uk/wp-content/uploads/2018/01/Planet-Autism-False-Accusations-of-MSBPFII.pdf
