      Set v = c to obtain Schwarzchild radius. https://en.wikipedia.org/wiki/Schwarzschild_radius …

      It’s a misleading coincidence that the Schwarzchild radius is where the classical escape velocity equals c, and this is often misexplained when introducing the concept of black holes

      well for one there's no reason newton's laws should be able to say anything about strong gravitational fields and be correct

      The gravitational field at the event horizon is not necessarily strong. Solve the problem for an extremely large black hole and then use analytic continuation.

      you can't get GR from analytic continuation of newtonian mechanics

      also at the event horizon there are plenty of relativistic effects not accounted for by newtonian mechanics (e.g. time dilation upon crossing etc).. black holes need to be treated relativistically

      No. You are thinking small black holes. Very, very big ones don't even have significant tidal effects. The biggest known (the entire Universe) is flat (total energy exactly zero.)

      that is precisely my point! you're choosing to just work in weak gravitational fields just so you can ignore relativistic effects

      this isn't my point though. my point is that using the newtonian intuition is bad form since applying gravitational effects to light is inherently relativistic

          But conservation of energy is not intrinsically relativistic. And _that_ is the basis of the escape velocity computation.
