Those 800,000 muslims are doing a pretty weak job of it then aren't they? If every muslim decided to do as you believe and take out at least 3 infidels, this would reduce the infidel population by 2,400,000. Have they had time to do this? Yes. Has this happened? No. Do they really want to do this? Evidence (facts, not opinion) suggests not.
As for lefty media - I had no idea that Rupert Murdoch was a socialist! Learn a new thing every day ....
