This is really a distraction from the discussion. Why is this semantical argument important to discuss? Although, if I were to answer it, "is" is not well-defined in physics. But "is" typically is understood to be "is modeled by". Yes, in general relativity, gravity is modeled by something different than what it is modeled by in Newtonian gravity, which is a force. General relativity didn't exist 300 years ago when gravity was difficult to accept. Newtonian gravity did. Models evolve but sometimes old models remain useful.
My entire point in this discussion was that we need new models to understand the complexity of modern society and human behavior. The old models aren't good enough. That's why I react somewhat negatively to complaining of conspiracy theories at an attempt to understand the complexity of the systems we've created and participate in.
This stuff is tough to understand and wrap one's head around. Even something as deductive, in a way, as Newtonian gravity and general relativity was met with great resistance, if not outright rejection. We shouldn't follow these patterns.
