You are aware rape usually occurs in private settings. Just because some one has decided to go to a private place with you does not mean they've given consent. And this kind of behavioural priming will gear men to steam roll over someone who isn't giving consent, hence sexual assault.
He doesn't say "Now, get her somewhere no one can hear her. Be sure to have your duct tape handy and then force your hand down her pants..."
It's a piece of advice on how to start being physical with a girl you're dating. So many guys will have a girl that's interested over to drink and watch a movie and just sit there a couch cushion away. Put yourself in your 16-20 year old shoes.
I'm assuming you don't really think that all rape involves having duct tape handy or making sure you're where nobody can hear her. A comment like this presumes that rape must be violent to be rape; that's simply not true.
