How to distinguish between feminists and radical feminists?

Anonymous
I have no problem with feminist people, but it is the radical feminists I have very much problem with.

So, girls... how to spot a one?
Because I am a guy and will eventually get a wife or a girlfriend, I need to be very careful about it. I need to find out discreetly whether the girl I am with is a normal one or a good one, a feminist one, or a radfem so that I can press the STOP button before the damage is done.

Hence, basically directed towards girls, but guys can also hop in to answer!
