I have never met a professional Evolutionist i.e. an academician who was merely an "advocate for evolution" and not a full-fledged "dogmatic believer in evolution". I haven’t met many amateur Evolutionists who fall in the former category either.
Really? Fascinating. I, on the other hand, have met and worked with both professional field and theoretical evolutionary biologists, and conversed with a fair selection of "amateurs" both live and on the net. In additiion, I read extensively in both the professional and open-published literature. I'll freely admit I've seen a lot of occasionally quite acrimonious debate among this crew over the details of evolution. In fact, I've engaged in some myself (an argument over the long-term ecological stability of the Cerro Kum concession, and another over the ultimate causes of the Posoltega lahar spring to mind). In my own field, there continues to be an often nasty argument between the advocates of Wilson vs Brown vs Whittaker concerning ecological equilibrium (I'm a dynamic disequilibrium-ist myself). The point being that IF your contention that we all adhere dogmatically to a "belief in evolution" is true, then there shouldn't be any argument at all, n'est-ce pas? Every single piece of evidence or bit of theory someone presents is argued over, fought over, dissected, and - sometimes - grudgingly accepted. Doesn't sound very dogmatic, to me.
Even if you choose to not to persue a career in biology following on your degree, I would urge you to attend at least one symposium where a controversial paper is presented, for entertainment value if nothing else. I'd be surprised if you can come away from one of those still considering "evolutionists" to be dogmatic...
