I would not say women are stupid but a fair few of them engage in stupid behaviour. The worst of women in general is a rampant insecurity which leads them to degrade and put down others in order to feel better about themselves. Personally I have less trust in the female gender in general because I have discovered them to be quick to anger, vengeful and more apt to engage in tit for tat kind of battles than the males I have known. All of that behaviour I find tedious and choose not to be around it.
