Serious topics such as politics and religion; Light-hearted topics such as games and music; everything is fair game. The most important concern is the truth.
I'm a practical civil libertarian with progressive tendencies and a religous view that doesn't fit easily into any category. For now, let's just say I believe there is a God (but I could be wrong), humans are not perfect, the universe is a big and old, and life is like good dark chocolate: bitter, sweet, and enjoyable.
