"Women must be on guard with men no matter where they may be."

I understand you think all men are rapists.   However, under Sharia law, rape can only be proven if the rapist confesses or if there are four male witnesses.  Women who allege rape without the benefit of the act having been witnessed by four men (who presumably develop a conscience afterwards) are actually confessing to having sex.  If they or the accused happens to be married, then it is considered to be adultery.

So while you may be right that all men are rapists, women are much safer in Western society.
