This Kate Forbes thing is a fuss over little. She is free to believe what she wants, people are free to withdraw support if they don’t like her beliefs. There is a question over why the SNP members were not bothered about something so obvious before, but it doesn’t detract from the point.
All this talk of how unfair it is that she is being damned fails to get how many SNP members might not subscribe to those views, find them disagreeable and don’t think someone like that should lead their party. Which they are perfectly entitled to do in a free country.
