Please go to your preferences page and make sure your "See Mature Topics" setting is set. Setting it to "Yes" means you see the Mature Topics forum (contains political and religious debates). Setting it to "No" means you do not see those threads.
While I certainly understand your privacy concerns, I am curious why you did not include any information on what interests brought you here. Maybe tell us how you found our site. Then again, you have every right to keep your introduction as short as it is now.
While you are here, you may want to check out the wiki and chat.
