The pro abortion brigade
Who's that? Anybody who supports abortion rights, I assume? That's me for one.
... seem to think that everybody wants their NI contributions to go to more abortions. They are wrong.
Except that you don't get to choose where/how your money is spent. There have been a few cases of pacifists witholding that (minuscule) share of their taxes deemed to be spent on defence. They were prosecuted, obviously, for the reason already given: you don't have a say in how it's spent.
And I will not give my opinion of Stella Creasey, or I will be modded.
A broader vocabulary would stand you in good stead here, presumably.
