What does but until in a sentence mean? I came across the phrase in a sentence that sounded almost exactly as this:
He was a great person but until he started caring for other people's feelings.
I have found another example of sentence, tweeted by Rupert Murdoch. His tweet was:
Maybe most Muslims are peaceful, but until they recognize and destroy their growing jihadist cancer they must be held responsible.
A compact explanation to this tweet would be real handy.
