That depends.
Have you ever used the phrase, “The Bible teaches…” (Jesus died to save sinners, God is a God of Love, Don’t judge people)?
If you have, then you’re a systematic theologian. Anytime we summarize all the Bible says about God, salvation, sin, etc., we’re acting as systematic theologians.
So the real questions is, “Are you a good one?”
Well?

Me, I muddle along better than some and not as well as others.
Your question reminds me too of an article I read where the writer talked about how some people criticize topical preaching as being inherently inferior to expository preaching (expository narrowly defined in this instance to mean taking a book of the Bible verse by verse). The writer said there’s a name for studying the Bible topically: it’s called sytematic theology and tons of seminaries the world over teach it.

P.S. Rachel Stone let me write a guest post today. It’s about food looking good and God being great: http://rachelmariestone.com/2012/07/03/pleasing-to-eye-good-for-food/
I think a key difference is that you’ve admitted you are a theologian and been purposeful about it. That alone makes you stand out among most people, Tim!
It’s like attending a 12-step meeting:
“Hi. My name’s Tim, and I’m a theologian.”
“Hi Tim!”
Haha – exactly!
