Like a true Marxist you align Keith with the Nazis. Keith is opposed to abortion laws. The Nazis prohibited abortion. Therefore Keith is a Nazi.
Seriously, you have it arse to elbow: go back and read. It's actually Keith aligning UK abortion law with Nazi law: "... the same reasons as the Euthanasia programme..." In Keith's view anyone supporting the right to abortion is inferred to be supporting Nazi style euthanasia.
My point is ironic: that whist making this claim a genuine eugenic anti-abortion Nazi law still extant in Germany whose aim was to turn German women into breeding stock is one he would support.
