I am very sorry about your experiences.

However, telling a person that stealing is a crime doesn't help.
They know theft is wrong.

Putting up fliers in school saying to get help if you are considering suicide,
increases the rates of suicide

Telling men that "no means no", what do you think it actually does?

What happens is that the good men DON'T EVEN ASK
50% of young men didn't have ANY sexual encounters last year.
Nice guys finish last? Nope, they don't even finish at all.

So, what happens with "no means no"?
You get good men staying away, and so your chances of meeting a bad man goes up dramatically.

And currently, in our legal system

Women can not legally say yes.

So, when more men figure that out, ALL of the good men will just stay away. And you get the exact opposite of what you want.
