That was no longer the case in the 19th c. I don't think a book written in 1879 is a very reliable source, do you? I've read that, and let's just say Campbell is not exactly pro-Ottoman. Or remotely neutral.
There were secular courts in operation where Christian testimony was taken the same as anyone else's. The religious courts - and all the faiths had them - were gradually restricted to family matters.
In a system where Muslims were predominant in administration, there is no doubt that there were abuses committed, but not particularly directed at Christians - more like equal opportunity exploitation. Most Europeans didn't give a rat's ass what happened to Muslims, though. The revolt in Bosnia and Herzegovina, for instance, wasn't sectarian, it was a general revolt against tax policy.
And in any case, I would rather be a Christian under Ottoman rule than a Muslim under British rule! There were Christian ministers and parliamentarians in the Ottoman government - no Muslims in the British, or any other European gov't - I think we have a double standard.
Of course the picture wasn't "all sunny" - but was it anywhere? This is only a few years after the Franco-Prussian War and the Paris Commune...
I doubt that would have been the case if Britain had a large Muslim minority on British isle, it's a little like if I complained about the lack of Danes in the Ottoman admistration, many European countries also had Jews or former Jews in their admistration.
