You're right but because it's no different from someone saying their specific solution is the only way. In reality, there are a multitude of different opinions and it seems likely to me that more than one would be effective.

Sure things might tend to distribute into two major positions but that doesn't mean nobody holds a different opinion and it says absolutely nothing toward whether those two solutions are somehow the ideal solutions (or one of them, in the case of the OP).
