Narrative:

I heard aircraft 2 announce that he was approaching igx from the south while I was approaching from the north. I announced my position on the CTAF. ASOS stated that winds were variable at 3-4 KTS. As I was getting ready to go into a 45 degree turn for a right downwind runway 27, aircraft #2 announced that he was going to enter a left downwind runway 27. When I informed aircraft #2 that igx had a right pattern for runway 27, I received no reply. When aircraft #2 announced he was in a left downwind runway 27, I again informed him that runway 27 required a right pattern. I stated that if he had an emergency, I would get out of the pattern and give him right-of-way. Again, no reply. At this point, seeing aircraft #2 on final, I did a 360 degree turn to my left to give him time to land. I then re-entered the pattern, proceeded to baseleg, and announced turning final. Aircraft #2 announced backtaxi runway 27. At this point I told aircraft #2 that I thought he had his procedures mixed up, and did a go around. His response was that I was out of line, that he had a sick baby on board.
