Women tiptoe around male anger about being rejected 24/7, especially on online dating. Lots of "evolved" males still become scary when turned down and don't handle rejection well. There is no way to filter them out because they all walk among us, they're our friends and brothers, and sometimes us.

Every woman who's gone on online dating can give you a list of stories of creepy, scary and/or off-putting experiences.

My point here isn't to start an online debate about gender equality, but to say: one of the main things that would help bring users to an online dating app is making it safer for women. If the women come, the men will follow.
