Basically, the Yes side would like to silence anyone that might have the capability of showing up their shortcomings. So they use emotive arguments, whereby it becomes impossible to have a sensible, rational discussion, because at any point an emotive point will be raised by them to siderail the discussion.
And they will twist, and twist that emotive point to get as much emotional blackmail out of it as possible. That's why I do feel its a bit morally repugnant. Theres something about doing that that sticks in my craw.
Its also why they really don't like getting back to basic common sense points. Such as the tax that pays for welfare benefits, and those who pay that tax.
Never mind, an independent Scotland, according to Nicola Sturgeon, will be sending all women out to work to pay those taxes.
