Is it Possible to Insult a Pro-Abortionist?

There seems to be criticism from pro-lifers of other pro-lifers, relating to comparisons made between pro-aborters and nazis.

This is apparently 'unacceptable' firstly because it diminishes, in some way, the horror of the Shoah, and secondly because there is no parity between the well-intentioned efforts of those who support 'a woman's right to choose', and the barbaric scourge of Europe 65 years ago, and such comparison is therefore insulting.

As to the first, the numbers speak for themselves.

As for the second, pro-aborters argue that the foetus is not a person, and is therefore less than human, an 'untermensch' to use the nazis' more robust language.

The nazis, after all, introduced abortion into Poland in 1940.

Perhaps I need re-educating, but for me it is hard to imagine an adequate insult for those who demean others in order to justify murder, whether 70 years ago or now.
