Here is my current understanding

For some external reason you are prejudiced against zero carb. In the heat of the moment you thought you would punch down on a tiny community by saying it’s dangerous that it exists, invoking the paradox of tolerance, implying it’s a Nazi type of thing.

When asked why a diet is something causes intolerance by tolerating it you realized you didn’t have a good reason for that statement. You have attempted to leave gaps for others to infer your reasons because stating them explicitly would show how inconsistent they were.

This entire comment thread has been a demonstration of avoidance.

If I’m wrong, please disabuse me of my conclusion.
