>How the fuck is pornography a hobby?
It can be observed if it's not treated as a job and it's for your enjoyment, you know, like every other hobby.
>How is it any different from religion in its consumption and purpose?
Religion is to sell you back the "morals" that were taken from you though your forced living under the local imperialist ideology, with bonus "morals" that weaken you either through: destruction of logic deduction, group isolation, do not question your god/master, etc.
After the transaction, it's then also given to individual the dysfunctional belief that if they don't observe their religion, they'll lose their "morals", and if lost, they're permanently isolated from society (figuratively or through death). The second communism is observed, religion is forever alive only in textbooks.
Porn's consumption is simply that if you're horny, a basic human nature, you consume it to subside it. It takes nothing from the user, making it's purpose simple, entertainment. The radical consumption of it today that is pointed to by the gang of rapists; the teachers of religion, is simply just the individuals needence to cope with their daily lives under their imperialist society. Same with video games, books, tele, etc.
