Liberal men, sexist pigs?

I analyzed General Social Survey data a few years and showed that liberal women are more likely than conservatives to report being victims of sexual harassment. My take at the time was that liberal ideology makes women define normal sexual advances as inappropriate and abusive. But now I'm wondering if liberal women simply work around many liberal men, and liberal men simply lack the old-fashioned chivalry found more often among conservatives.


Here's a replication:

Percent reporting sexual harassment over past 5 years

Extremely liberal  23.7
Liberal  18.9
Slightly liberal  19.5 
Moderate  16.7  
Slightly conservative  19.3
Conservative  15.9
Extremely conservative  10.3
