Major props for having the chutzpah to list NORML, but this is a polarizing issue that some people will simply react very negatively to no matter how much justification you offer. Sort of a microcosm of the current state of prohibition, when you think about it. I'd like to be able to say that well-reasoned argument would change the mind of the average adcom fossil, but I don't think anything but time will fix this particular generation gap.
This is roughly on par with listing your membership in a pro/anti choice group - some will love it, others will hate it, but alienating half of the people whose votes you need is the kind of tactic that only works in a safe congressional district. You're in a very different spot - with average stats and ECs, it really only takes one person to blackball you.
Unfortunately this is a situation where people will not respect your courage, especially because having this as your unique activity will almost certainly get you nicknamed "the pot guy".
