Woman who falsely accuse rape deserve just as hard a sentance as rapists as they both destroy lives. Sadly we live in a society that often assumes "no smoke without fire" meaning a man falsely accused will have it carrying over them for many many many years.
In fact the government itself is propogating the "no smoke without fire" attitude by proposing to tell mothers where a partner has been accused of abuse in the past despite being not charged or found guilty. That is morally wrong. Innocent until proven guilty and all that.
Although i agree with SassyRS's point about prick teases/wind up merchants, it still doesnt mean a man has any right to rape a woman (or man to be pedantic). Any man who cant control himself deserves locking up. Thats just one thing that separates us from animals, we have the capability to control our sexual urges.
Its about time both sex's took a bit more responsibility for thier actions really.
The really grey area comes with "capability to consent" and with the number of people who get massively drunk or out head on drugs theres always the danger signals can get mixed and the fact that people may be soo out of it they just dont know what they are doing. Obviously if one partner is unconcious or incoherrant then its obvious they cannot consent to sex. The problem comes when both partners are off thier heads.
Its not surprising that with more people than in past getting totally wasted and having casual sex then there will be more instances like this occurring.
Also i do think woman need to look after themselves more when they go on nights out. Getting blind drunk with no way of getting home and no mates to look after you means your very vulnerable to sexual predators.
