You do realise it's not like someone runs up to you and says "HEY LEMME GROOM YOU GIMME DAT PUSAY"
they take time to befriend you and make it seem normal, and for a lot of people they don't know any better
You don't seem to understand that some people don't think that they are threats and have not been told any better. It's not fair to oversimplify the problem to just ignoring them asap.
You gotta keep in mind half of these bozos are middle schoolers who cant use their brain. That is something that they acknowledge as an option when its too late
