"So she cant stand up for herself why? Why should our society encourage “decent” men to speak for women and protect them?"

The women in question did stand up for themselves. Hence all the public records that were posted by a "decent" man. 

Society should encourage men to speak up for women against rape culture as well against people like Mr. Brown. This webiste was put up with the knowledge and consent of the victims. 

Nobody is advocating for an accusation based legal system or having "decent" men speak FOR women. Men need stand with woman and encourage their voices to be heard while at the same time lending theirs. That's exactly what happened even if you can't see it.
