I really don't understand why, previous to this furore re mothers/non-mothers, Theresa May found it necessary to discuss her childlessness. It is absolutely nobody's business but her own and, in my view, it has absolutely no bearing on whether somebody will do good job. I also don't think their religion is of any consequence either - many of the politicians whose actions have, in my view, been despicable also profess to be Christians.
My feeling is that if Andrea Leadsom made the comments ascribed to her (and apparently she denies that she did), it really confirms what an underhand, bigoted and silly woman she is.
I think these women do all women a disservice by entering into a discussion about something that would never be required discussion material for a man.
