Pilot reported that while beginning the takeoff roll; another aircraft on final performed a go-around to avoid a near midair collision.

Narrative

I announced my taxi from Parking to the active Runway XX. Approaching a taxiway intersection; I queried on CTAF whether there was any traffic in the area; to which I received no response. The only traffic I saw via ADS-B was about 6 miles to the west of the airport. As the parallel taxiway doesn't extend the full length of the runway; a back-taxi is required for Runway XX. I didn't taxi to the end of the taxiway since there was no one in the area; and instead turned on an earlier taxiway to back-taxi. Once I was on the runway and taxiing; I heard a radio call; 'Aircraft X; why would you back-taxi from there instead of going to the end?' To which I responded; 'My apologies; I didn't see or hear any other traffic in the pattern. I can of course taxi faster on the runway and will expedite.'Immediately after; the other aircraft made a downwind call. At that point I noticed that according to ADS-B; the aircraft was still showing about 3 miles west of the airport. As I turned around at the end; the other aircraft made a base call. As I lined up with the runway and began my takeoff roll; I saw that he had turned a short base with a flight path in front of my aircraft. By my estimate; he had turned base approximately 1000 ft. prior to [the] approach end of the runway. Shortly after starting the turn; he made the call; 'Aircraft Y going around for the goddamn Aircraft X.' Though he announced the go-around; he flew his aircraft in a descending flight path towards my aircraft. I'm not sure if he was attempting to 'buzz' my aircraft or not; but as my aircraft out-accelerated him; he made an abrupt pull up; back onto downwind.In my opinion; his aggressive maneuvering was an airborne version of 'road rage' in which he put me; my passengers; and himself in an unsafe situation. I attempted to talk with him after my short flight [of] 8 minutes to debrief the situation; but he had pulled into his hangar and left very quickly after. This gentleman owns the hangar next to ours and frequently expresses his opinion that we're not welcome at the airport; I've never met him myself. In his attempt at creating another situation to complain about; he put multiple lives at risk.
