Just a tip: referring to fetuses as parasites does not help the pro-choice cause. It is too emotive (in a very negative way).

Despite being pro-choice myself and agreeing with Conlang on (at least) the main points of the argument, I almost feel like hearing people use the word "parasite" to refer to fetuses almost makes me want to jump on the pro-life bandwagon.

Having seen the heartbreak that my sister, my wife, and other women have gone through after miscarrying what is being referred to as  a "p.......", I would have to say that the use of that word is not helping anyone.
