There are people in this thread saying even doing it as a bar isn't okay anymore. Name one place where a man would be safe asking without potentially being called a creep even just for a polite inquiry. It sounds like there isn't one anymore.
Not all women would react that way, but it sounds like there are enough women who think that's an acceptable response even in a bar that it's nonlonher longer viable.
And yet I don't think raping someone is an acceptable response to being rejected and yet its still okay for women to treat all men like they might do it. So why should men not treat all women like they're going to cause problems if they get approached?
