Just an observation-- Some (how many I do not know) but; I suspect primarily older Americans dislike the PK method of deciding soccer matches for the same (but not consciously considered) probable reason they dislike soccer in general. They have an inherent dislike for the (at least perceived) egalitarian nature of its rules. They dislike rules that attempt to make it as difficult to score as possible so that teams that are inferior in overall talent are afforded a better chance at upsetting more talented teams. Those with this mind set inherently prefer to see the more talented teams nearly always totally "crush" their less talented opponents by large margins.
