Oh Sam Harris, yes.* Even moreso than Dawkins (because Sam
  Harris is more well rounded), I have friends that seem to quote
  nobody else BUT Sam Harris for every point they want to make.
  I've only heard mention of PZ Myers once - I should look up. I
  doubt I'd ever be atheist myself.* I've had people try to pin me
  down with the standard 20 questions when they hear I'm agnostic,
  and then they either try to get me to "admit" I'm atheist or
  theist or some ridiculously made-up categorization chart that
  seems to make sense to them. So some decide I'm a closet
  atheist.* Some decide I'm a closet theist.* Or a closet
  something else - I dunno, I don't pay it much mind and find
  their little courtroom style games amusing. I'd say above all,
  I'm a skeptic.* There's things I genuinely don't know in the
  world and I'd say in the percent of knowledge vs not-yet
  knowledge, the not-yet-knowledge is likely far greater than the
  knowledge. But I'm grateful for what we've learned so far. So,
  I'm agnostic about many many things.* For me, it's more an a
  general attitude of having a few good all-purpose "bullshit
  detectors", usually boiling down to various sets of heuristics I
  apply depending on the situation, some of which include various
  methodologies and others which are simpler than that and are
  basic rules-of-thumb.
