Re: Also there is apparently no law against
Or by virtue of fraud, raping women protesters and fathering children by them
I think if you accepted this one, you would be on a very slippery slope indeed. It would mean that every white lie anyone ever tells to have sex could be brought up against you later, ranging from shaving or adding a few years here and there, to exaggerating the size of your penis, job importance, wealth or whatever. You consent to sex if you like the person you are with, regardless of his/her job title.
Your cynical points about all the others have validity though
