Rape Myth #1: Women make false rape accusations all the time
Bullshit.

According to the FBI, only 8% of all rapes reported in the US are "unfounded" but not necessarily false. (http://www.fbi.gov/ucr/Cius_97/96CRIME/96crime2.pdf) 1997 was the last report in which they calculated that.
Figures in the UK bear this out as well. (http://www.homeoffice.gov.uk/rds/pdfs05/hors293.pdf)

Here's some statistics from http://www.rainn.org
Only an estimated 40% of sexual assaults get reported.
Of that 40% only 50% of those will even be arrested.
Only an estimated 6% of rapists will spend a DAY in jail. Not prison, jail.

On this page of the RAINN site: http://www.rainn.org/get-information/statistics/reporting-rates
It shows a tree of the disposition of reported rapes.
If you want you can go see it. I did the math, it works out.

So, as a means of vengeance, false rape reporting has a really piss poor chance of coming to any fruition. I mean, there's only a 50/50 chance the victim of a false report will even be arrested. Seriously, there are way more effective and sure ways to get revenge.

Ok, now apart from the fact that it's highly unlikely to come to fruition, add into the equation that when a woman accuses a man of rape, her entire life is turned upside down and put under a microscope. Her entire sexual history will go on trial. She'll have to justify every sexual act she has ever performed with anyone ever. She'll be accused of being a promiscuous whore who wanted it. Her clothing will be scrutinized. Her comings and goings. Does she drink? Does she wear a thong? Was she wearing lacey underwear?

And if you thinks it's only adult women with suspect motives who are on the receiving end of these questions, just read the transcripts from a few child rape trials as well. Seriously, it will turn your stomach to hear defense lawyers and defendants telling a jury in all honesty that a ten year old girl wanted sex.

The US and UK legal systems are not friendly even to women who come to them with a mountain of evidence, how much less friendly do you think they are to someone with only a story? Even when the story is true, it's almost impossible to get a charge of rape taken seriously, even if you are a grandmother, nun or child, particularly without evidence.

Ok, so all that aside, of the 40% of all rapes, the ones that actually get reported, only 8% of that 40% are unfounded, not necessarily false, just lacking evidence. Some of those are victims who are bullied in recanting by their families and friends, or out of fear of the rapist or his family and friends.

Given how I've seen actual rape victims treated, pretty much with all the tact and sensitivity of raw liver, very, very few women would ever willingly put themselves through that to "get back at" anyone. Seriously.

Think about it.
