I've done it, too. I was a born-in, so I never experienced anything in the world. Spent time as an elder, pioneer, etc. Finally saw the flaws in the borg and disassociated at age 41. In the year and a half that I've been out, I've done some desensitizing, too. And I've done it for the exact reason you gave. It has been a way of forcibly breaking my subconscious resistance to breaking the wt's rules.
The night my DA letter was read, I planted an American Flag in the front yard. I now smoke, even though I know it's a harmful and stupid habit. I have watched The Exorcist, Paranormal Activity, and several other "demonic" movies. I went to a fortune teller and had my palms read, plus had my tarot cards read. I registered to vote. I've donated blood as frequently as I'm able to. I participated in a Catholic mass (even though I'm atheist now.) I've done all of the holidays. My house had the most Christmas lights of any house on my block. (My neighbors were probably like... wtf?? Since when do we have to compete with THAT guy???)
One thing I haven't done is fuck around, but that's because I love and respect my wife. If I wasn't married to her, I would do whatever the fuck I wanted to do.
Basically, I look at it this way: I gave the first half of my life to the lies of the washtowel under the guise of worshipping j-ho. I am dedicating the second half of my life to disrespecting j-ho in any way I can.
