But how does choosing the craziest of the crazy to represent a position you oppose?
I strongly disagree that it's the "craziest of the crazy". I've seen similar assertions made by relatively normal people. Such claims have even been made on this forum, in similar threads, in the past. What I think it is, is an emotional reaction overcoming reason; people parroting poorly-understood rhetoric rather than rationally evaluating the issue and proposing a workable solution.
This is a very emotional subject, and it can be very difficult to think about calmly and rationally. Indeed, for many people, attempting to do so is seen as devaluing the problem, because of its emotional impact; and the more emotional things become, the more emotional they
can become. So irrationality tends to become the norm rather than the exception; and the tenor of debate devolves into unhelpful rhetoric.
Even the nature of the rhetoric tends to degrade over time because of this; as each new generation picks up the banner of irrationality. And it is understandable that this happens. Women have traditionally been devalued as second-class citizens; and rape is notoriously under-reported and under-prosecuted, with more victim-blaming than nearly any other crime. There's a strong cultural bias at work; which tends to produce rage and despair in its victims, making it much harder to retain a rational mindset. Opposition to the emotionalism becomes increasingly lumped in with dismissals, and those calling for reason tarred with the same brush as denialists and victim-blamers. Nuances of the debate are lost as the issue becomes increasingly black and white, Us vs. Them, and false dichotomies abound.
So what we see is that relatively reasonable rhetoric slowly devolves into reactionary polarization and useless name-calling. "Because of the history of rape prosecution, greater credence needs to be given to victims" becomes "Women should always be given the benefit of the doubt in cases of rape", which becomes "Women should be assumed to be telling the truth about rape without overwhelming evidence to the contrary", which becomes "Women never lie about rape". "Consent is a complicated and potentially difficult issue", gives way to "Consent needs to be clear and obvious, and there are circumstances which should be assumed to invalidate consent", which gives way to "Consent cannot ever be assumed, even if the woman says yes", which eventually gives way to "Consent is not magic; any time the woman says it was rape, it was rape".
This attitude again rears its head when the issue of male rape is brought up; and the rhetoric goes from "Male rape is an unrelated issue, statistically far less frequent, and not what is being addressed in this discussion", to "Male rape is unimportant", to "Male rape does not exist" to "Rape apologists are trying to devalue women with 'Think of the poor menz!'".
This lack of reason feeds on a similar lack of reason and creates an equally adamant and irrational opposition. "The problem is complicated, and needs to be studied, and better ways to differentiate between true and false claims needs to be found", is treated as "You're exaggerating, it's not as bad as you claim", which is treated as "The problem doesn't really exist, things are fine the way they are", which is eventually treated as "Crazy man-hating feminazis saying everything is rape".
After a while, groups start to define themselves by their black vs. white "purity" on the issue, and you end up with a lot of people trying to make their voice heard without really understanding the issue and its complexities. Since reason is no longer welcome, they're left with repeating the appropriate rhetoric, rather than risk being seen as "apologists" and "denialists", or supporting "radicals" and "crazies".
The problem is not that anyone is "crazy; that's just a too-convenient dismissal of the real problem - emotionalism increasingly overcoming reason and shutting out all rational debate.
