The SO never appealed to me. When I got into scn the war in Vietnam had just ended and I considered myself very lucky to have avoided it. Anything quasi-military had no appeal for me. Having taken LSD was certainly a very convenient "out." Chucking out everyone who'd taken acid would've eliminated too many people. The same people who took acid were the same ones who were likely to try scientology: those who were a bit more broad-minded and likely to try new things, even if they were a bit kooky.
