Why can't St. Louis Cardinal fans get over Don Denkinger's bad call?

In Game 6 of the 1985 World Series the Cardinals held a 3-2 series lead and we're on the road in Kansas City playing the Royals. Heading into the bottom of the 9th the Cards were up 1-0 when Todd Worell came in to close out the game and the WS Championship for St. Louis. The first batter for KC was Orta who hit a slow grounder to the first baseman and Worell went over to cover 1st for the force out. Yes Orta was clearly out but Don Denkinger the umpire called him safe.

After that the Cardinal Catcher miss played a foul ball which would have been an out instead KC got a base hit. Then the catcher let a past ball occur allowing both runners to move to 2nd and 3rd and into scoring position. Next KC got a base hit and the catcher missed the tag at the plate allowing both runs to score giving KC the win and the series tied at 3-3. The following night with Denkinger working behind home plate the Cardinals lost game 7 -11-0 and the Royals won the World Series.

Since then the Cardinals have won 2 World Series but they STILL CAN'T LET IT GO. I am a Cowboys and Mavericks fan and I got over Dwight Clark's catch and the mavs choking away the 2006 NBA Finals, and one day I will get over the Rangers choking away the 2011 world series. Why are Cardinal Fans 28 years later still BITTER about 1 bad call. Denkinger didn't miss play, drop a pitch, or miss a tag, and don't forget game 7. Cardinal Fans please explain
