The major problem with this is that the KKK was tolerated, as a group, in the region.
The difference? If France tolerated an Islamist group running around killing Jews, then yes, I'd say they don't have de-facto religious freedom. The KKK wasn't legally punished for their actions in the region they operated in for simply too long. Now, yes, for the most part, this was a specific region of the U.S., and not the entirety of it, but that's another matter.
Religious freedom requires that the state enforces it, not only that it's de-jure in existence. Otherwise, popular pressure can enforce de-facto religious monopolies, which yes, I'd argue is not religious freedom.
