Yeah, he was heavily criticized in articles, by active military who viewed his getting to join in on training as an insult. Thats him being hated.
His upbringing, the way he was pushed and also his celebrity as a teen, has been heavily criticized thru the years. Thats him being hated for those things.
Earl was a lightning rod for controversy and parental criticism. Tiger was criticized for the perception that he was favored over siblings. Tiger has been tied to comments that Earl made, which were criticized. Tiger was expected to justify things Earl said and Tiger defended him, to the point of also being criticized. That is him being hated. As for his dad dying a long time ago...I am clearly referring to before he died. Tiger has been a pro for over a quarter century and was a household name in golf for a handful of years before that. Earl was around for Tiger's first decade as a pro and it was a dominant decade- one that had Tiger on magazine covers all the time, winning constantly, and a focus for fans both on and off the course. Just because Earl has been dead for 16 years doesnt change what happened in the decade prior.
