After entering the traffic pattern using a 45 degree entry; I was established (and reported such on the Unicom frequency) on the left downwind of the landing traffic pattern. Other aircraft entered the traffic pattern on a crosswind leg at midfield from which he was going to enter the same left downwind leg that I was flying. At same altitude (traffic pattern altitude) he passed in front of me by no more than 150 feet while beginning his left turn to the left downwind leg. I commented that he had just cut me off and we had come to within 150 feet of each other. He responded that he never saw me. While it was day VFR; I had my aircraft illuminated with landing lights; red tail strobe and wingtip strobes. We had a very heated exchange on the ground. It was clear that he had no clue who has the right of way in a traffic pattern; or that he would ever admit he was wrong. (As a side note; he arrogantly stated: 'I'm a retired airline Captain with 25;000 hrs; what are your qualifications?'  When I replied that I was also a retired airline Captain with the same amount of flying time; he told me to 'get the [expletive] off 'my' ramp. I told him the ramp was [not owned by him] and left. A loose cannon for sure.
This ATP pilot; flying a small single engine G/A airplane in the traffic pattern at an uncontrolled airport and conforming to expected radio protocol; reports a near miss with another aircraft apparently not communicating.
