Ugh - no, it was not a "fearful response" to any of that. Don't overthink what this was all about. It was a gimmick promotion thought up by Mike Veeck, Bill's son, as yet one of many other promotions they came up with to try and draw people into Comiskey Park at a time when the team really stunk. They had a wild promotion almost every single night back in those days.
The disco fad was coming to an end anyway, and so that combined with this new, young, popular DJ in town in Steve Dahl, who had recently gotten fired by a station that turned from rock to disco, provided the perfect storm for this particular promotion. And that was it - the gimmick-driven Veeck partnered with a rock-driven DJ whose only beef with disco was that it led to a recent firing. Nothing more, nothing less.
