A single instance does not establish a pattern. Only one woman's experiences are communicated and the "study" they link to is just a tacky video featuring full-frontal nudity of 70's German women. Then the article quotes "scientific socialism." I believe what they mean is Lysenkoism - which is the worst kind of approach to science since raw superstition.
Now, it may be true that women in socialist environments enjoy sex more than their democratic cousins, but this survey does nothing to prove it. To claim otherwise is simply not supported. Thank god the author had the presence of mind to make the first word in the article's title "Opinion."
It's really shameful of modern written media to be advancing this kind of lazy propaganda. I can only imagine how many morons are going to take this at face value.
