Should society shame people who watch porn?

Absolutely. Anything haraam would have to go under the (inevitable) Sharia system thats on the way...

Food addicts (fat people) are shamed. Smokers are shamed. Drug addicts are shamed. Gamblers are shamed. Shopaholics are shamed. Alcoholics are shamed.....

Of all the major addictions which blight society, only the porn addict is spared from societal shaming.

Porn addiction is just as damaging as any other addiction. It ruins lives and destroys relationships. like the other addictions, it ages people prematurely.

Even though porn is the most shameful and degenerate of all the vices -- which is why people do it in secret -- its still considered the most socially acceptable.

This contradiction has to change if society is to combat porn addiction, and it must start with shaming porn watchers.

The question is why isn't society doing this already?

There is nothing shameful about consenting adults expressing their sexuality. There is nothing shameful about work. There is nothing shameful about sexuality or openness to experience. Ethical judgements against the expression and depiction of human desires and sexuality shame the people involved in speaking to something that is deeply human and hides it in a closet to become perverted and judge the most vulnerable people. It's a victimless crime and you are the problem. If you think porn is the most degenerate and shameful of all human voices you need to listen to others and learn compassion for the level of human suffering that exists. Addiction is a terrible thing and thinking you will fix the world with more shame perpetuates the problem.
