Let's not fall into a death spiral around the dictionary definition of tolerance. I think you would agree weather something should be tolerated under the policy of "tolerance" depends heavily on whether that thing acts to defeat the more fundamental purpose for which the policy of tolerance is instituted in the first place.
If the fundamental purpose of tolerance is to actively preserve a wide range of points of view, for example to promotes improved collective decision making, then it would be folly to tolerate one particular point of view that acts aggressively to suppress many others for a purpose decidedly not shared by the majority, as Islamists often tends to do.
