I fail to see why frame material matters. I imagine that most of us active in the road bike sub-forum probably ride CF bikes. Maybe I'm wrong, but CF is just another material that bikes can be made out of and I don't see where there are enough unique things to discuss about them.
There'll always be those that claim steal is real. I've even seen some threads where some didn't want to ride anything but aluminum bikes. Segregation will just lead to continuing ignorance and myths. Lets face it, we all need to learn how to get along with each other, no matter what our bikes are made of.
