Jim Knight,
Over the years I've run into a few other people like you, who absolutely hate the taste of pronghorn meat even when everybody else eating it really likes it. A number of years ago I began to suspect that pronghorn meat contains some chemical that only a few people's taste buds react to--much like cilantro. To most people cilantro tastes fine, but to some people it tastes like soap.
One of the people I know who hates all antelope meat is Bob Nosler, who simply can't eat it, even from a relatively mild-tasting antelope like a well cared-for young doe.
