I would refrain from saying anything more than a general statement that shows your personal interest in that particular cause during recruitment. If you join a house and feel comfortable being more specific later on, go ahead. But even if the member you're talking to during a party is a total sweetheart, if you bring up your personal experiences (even indirectly) she might go deer-in-headlights. I would, personally. Some people just don't know what to say without making the situation even more uncomfortable and it just all falls apart. Just express your interest in helping raise money and awareness for their philanthropy and since you're obviously sincere about that, they'll realize you'll be an active participant in philanthropy activities.

In otherwords, I wouldn't say that you can "relate to it" during a recruitment party because if you get an awkward annie like I am it could turn into an unpleasantly stilted conversation during the party. Just be yourself and the fact that you really do care about the cause will be obvious.
