the SPD effectivly legalized abortions in 1920, by repealing §218 stgb, which stated the penalties for abortions.
Of course the NSDAP did exist then, but they could not write laws.
1928 they had 2.6% of the vote.
1933 the NSDAP voted to reinstate § 218 Stgb, which reinstated to penalties for abortions.
Claiming the NAZIs had anything to do with 1920ies legislation in germany makes about as much sense as claiming that Jill Stein and Ron Jonson have
major influence on 2012 US legislation.
