Diane and I were often accused of being the pom-poms type when we ran with FedEx Custom Critical, I think mostly because our success with that carrier challenged the comfort zone of the pom-pom insult slingers. That may have been because of a natural disposition to tear down successful people, or it may have been because those tossing out the pom-pom insults had an ax to grind against FedEx and did not like to see visible success stories originating out of that carrier.
The phrases "pom-pom insult slingers", "natural disposition to tear down successful people", and "visible success stories" point to an alternate explanation: the portrayal of yourself as very successful, and others as very resentful of it.
There may be some who resented your alleged success, but there are unquestionably those who resent your superior attitude in writing about it.
PS Cheerleading is merely an expression of enthusiasm - it does not require a basis in fact, just enthusiastic support. Sometimes the cheerleaders are genuine, some are misguided, and some are paid to wave the pompoms - it's up to the observers to figure out which is which.
