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.
Diaperspace also has a large number of listings by country/state/providence. Just be careful contacting people b/c you never know what you will run into there. I've been lucky in that aspect so far... met a really nice person who is local to me... but I see others listed on there who I am not particularly interested in meeting.
