All I disagreed with was your statement that "everyone knows why women withdraw their allegations". I did not dismiss any actual reasons advanced by women on this thread.
There is plenty of anecdotal evidence, but we know that anecdotal evidence can give a false picture. That is why I would like to see a proper study. Why are you against such a study?
The available statistics do not support your argument that the majority of rapists are repeat offenders. There are a small number of serial perpetrators, but the majority are not repeat offenders as far as we know.
No convicted rapist will serve a sentence measured in months unless the judge decides to ignore the sentencing guidelines. The absolute minimum sentence for the least serious cases where there are substantial mitigating factors if 4 years. It is extremely rare for a case to attract a sentence that low. The average sentence is 9-10 years and can go as high as 19 years for the most serious cases where there are aggravating factors.
You say it is not substantiated that introducing capital punishment would inevitably lead to people being executed for crimes they have not committed. Given that we know that this has happened throughout history whenever capital punishment has been used, what kind of substantiation do you need? Or do you prefer to simply ignore the evidence?
I'm sorry you don't care that your policy would have resulted in Andy Malkinson being executed for a rape he had not committed and, in all likelihood, Paul Quinn, the real rapist, would never have been convicted.
It is precisely because I do care about the women who are raped that I want an effective solution. Capital punishment is good for people who want revenge, but it has never been effective at preventing crime. The only thing that works is the certainty of detection. If you really care about the women who are raped, that is what you should want.
