As you yourself stated at the beginning of the highjacked thread:
it is perhaps understandable that people started talking about your “background” material instead of your actual suggestion. As part of that background material, my contribution (late in the conversation) about making the front and back faces have the same material doesn’t, in my opinion, rise to the level of “highjacking” a thread. Did it divert from your intention of your original post? Yes. I don’t dispute that. Was it inappropriate in context? No. Nor was the initiation earlier of discussion regarding front/back faces - since you included that as part of your background material.
