Here's how to deal with those hordes of self-styled "refugees" groping women all over Northern Europe:

Enroll them in "No Means No" classes like the ones on college campuses!

Really! This is what they're doing in Norway:

In Norway, migrants are being given courses to prevent violence against women, especially rape, and to teach them how to interpret customs in a country that may seem surprisingly liberal to them.

Here's a sample class:

This particular morning at the Ha reception centre in southwestern Norway, a dozen Syrian and Sudanese asylum seekers fidget in their seats in a small room as their group discussion starts.

The curtains are drawn and a space heater blasts out hot air to heat up the room, but the participants keep their jackets on.

"The idea behind this course is to talk about risk situations that can arise when it comes to rapes and sexual assaults," the group's leader Linda Hagen says, kicking off the class in Norwegian, with an interpreter translating to Arabic.

"We need your help so that we can together detect these situations."

Don't you have the feeling that these fidgety Syrians and Sudanese aren't going to react in quite the same positive way as 18-year-old computer-science majors at Podunk U. here in the States when Hagen informs them that not every girl twerking with them in a miniskirt wants to be their sex partner.

And you're right! Here are some Syrian and Sudanese reactions to Hagen's lecture:

"If she wants come to my place, that means she's consenting," says one Syrian.

"But if she's drunk, how can I be sure that she wants to sleep with me?" asks a Sudanese man.

Here are some more:

The need for the course — which is organised by Hero, a private company that runs 40 percent of Norway's reception centres — is exemplified when a video normally shown to secondary school students is screened.

In the clip, a party is in full swing. Two teens are making eyes at each other and they kiss. The boy pulls the girl, visibly tipsy, upstairs to a room and locks the door behind them.

He becomes increasingly physical with her, despite the signs of resistance she is displaying. "No means no," concludes the video.

But the video meets with a range of reactions from the participants.

"He tricked her but the girl should also have been clear and said no and not gone upstairs with him," says one.

"If a girl kisses me, I figure she wants to sleep with me," says another.

Uh-oh! Not going well!

Linda Hagen intervenes, explaining: "In Norway, it's quite common to hug, to entwine, to dance very closely without it necessarily leading to a sexual encounter."

Oh, OK–I'm sure those Syrians and Sudanese now understand!

Hero launched its course after a series of rapes committed by foreigners in the southwestern town of Stavanger between 2009 and 2011.

"We invite the residents, both women and men, to have a dialogue about cultural norms and to take responsibility if they see something," says Hero's director Tor Brekke.

"It's not a magic formula, it's just mostly about making an arena for dialogue."

That "dialogue" could take a while. Police statistics released in 2011 indicated that 100 percent of violent rapes reported in Oslo, Norway's capital, involved male immigrants from non-Western countries as perps, and 90 percent of the victims were native Norwegian women. And that was five years ago.
