I think they do understand what normal families are like. Look at their policies on women they are suggesting that they will introduce policies that mean that both parents can properly share maternity leave and take their parental leave at the same time.
labour have brought in crazy policy that the man can only take it if the woman does not and both parents cannot take leave at the same time
Background is not relevant, it might have been one hundred years ago, but these days there is so much more information. Of course they understand what life is like or they do as much as any of the political classes do.
Vote conservative. Britain needs a change, I cannot face another four years of same old same old, more bureacracy more damage, more state, less freedom.
