Popper was specifically referring to levels of intolerance that cause people to move from the world of discussion to the world of physical force.

That is, per Popper, tolerating people who will physically harm you as part of the discussion means a discussion cannot be meaningfully held at all.

But people really like to stretch this to whatever edge-case meaning of "intolerant" would be convenient to them at the time...

Well, the law certainly represents physical force.
