Last weekend a friend told me that they're involved in an activist group that focuses on political education for people with learning disabilities and severe mental health issues. The activists' reasoning is that this group of people is very susceptible to fascist narratives, and prone to social isolation when they start adopting or simply repeating fascist world views.
Fascists of course have no trouble claiming that support as validation for their politics, and votes are votes, after all. One could even argue that fascist propaganda inherently targets people with reduced intellectual capabilities.
This post made me think of that.
