Thanks for your response. I feel for women, and the dangerous and creepy men they have to deal with.
But here's the thing. Pick up artists teach men how to approach women in a way that isn't threatening. They actually teach men all about the daily uncomfortable experiences women have so they better understand how to interact with them.
Why do pick-up artists teach men how to be non-threatening? Because they're such nice caring people? Not really. They teach this because acting creepy and threatening doesn't get results.
Pick-up artists only care about results, and making a woman feel threatened or creeped out doesn't produce results.
For example, a pick-up artist would never catcall a woman. Why? Because it simply doesn't work. No woman is attracted to a man who catcalls them.
