I am not going to debate but if I remember from past threads, you are applying to colleges at age 15 and only want certain colleges that dont waste your time with too many prerequisites and will allow you to mostly only take courses about financial and investment banking.
What about you being an activist shows you will be successful in your chosen field? I would perhaps focus on how what you are doing now helps you for your future. AO may see it either way and feel its a positive or a negative but I think you need to be true to yourself, list it, and accept their decision whether its a yes or a no. However, I could see you attempting to claim ageism if you do list it and they decline you for admittance to their college (even though they may be saying no for many other reasons). In time you will find the right school for you. You need to do what you feel is right for your own conscience and deal with the consequences both good or bad.
