Why are body parts porn for some people? Why is skin made out to be something dirty or objectable?
Do you walk around in a potato bag?
I don't see it as any different than the extremists who flog people (well, women really) in islamic states just for unveiling their face for a second to catch a breeze in the burning desert.
Fuck your world view. Really.
Go to Sudan, Congo or the Amazon and tell all those people they're indecent & lewd for walking around with no clothes in 55c temperature all their life.
Here. Here is some porn for you.
