I had the notion earlier this week that elements of the far right recognised that they have very little support among women and that the left (socialist) has significantly higher support among women than men (here in the UK this is true at least).
This led me to the belief that this "REAL WOMEN" thing is actually partially about creating a fascist segment of women within society.
Also I hate to invoke harry potter but going through people's family history and records to check whether they are or are not a real pure blood has the same energy as the fascist supporters of Voldemort.
