If we talk about tolerance as a peace treaty (which the article encourages us to do) then I might rephrase what you said slightly differently:

"Holding people to account for breaking the treaty is not the same as breaking the treaty"

If you accept my rephrasing, then I would like to argue that many things which people claim as "taking a stand against intolerance and bigotry" are themselves acts which break the peace.

If tolerance is not a moral precept then it cannot in any sense belong to an ideology.
