Here’s an advertising tactics atheists might want to use with their own billboards.
In Bnei Brak, an Israeli city with a super-conservative religious population, a lot of men don’t like to see images of women dressed “immodestly.” That means their elbows and knees and hair must be covered at all times.
So advertising company Twisted came up with a clever way to raise awareness about the need to stop violence against women.
They put up this poster, knowing it would get vandalized by the ultra-orthodox men:

Less than 24 hours after it went up, the face of the woman was ripped off… revealing a hidden message:

International Day for the Elimination of Violence against Women
25.11.13
Very clever. Very effective.
If only we could’ve seen the looks on the vandals’ faces…
