Welcome, RetroGunslinger!! I foresee you becoming a great contributor to this here forum in the near future.
As for Bowie and being an atheist, you have that in common with my husband ktspktsp (that's his handle around here)... and as for being opinionated and loving debates, well that's right up my alley. So we look forward to getting to know you better through your posts on the TFP!
Oh yeah, and movie discussions are very popular here, so you're going to fit right in.
Have fun!!!
