Very true. As I said, helmet-to-helmet is part of illegal helmet contact. In this case, it's roughing the passer. It might be targeting. it might not. It might be spearing. It might not. Since targeting at the high school level does not include an automatic ejection, the words we use are not as important as they are in NCAA where targeting means an ejection.
FBRef is correct that there is rarely concensus among officials, so consistency is very hard to come by. Ther are sites where guys from all over the country can look at film and comment. There wll be plays where half the comments say targeting and half say it isn't. There are some that are nearly unanimous verdicts from the film, but were called differently in real time at game speed. It's a very hard call to make.
I've had one targeting call this year and it was on a kickoff return, not a play from scrimmage. Even that was hard to see on the video. When it happened, I had a flag on a member of the kicking team. Another member of the kicking team asked "That was targeting, wasn't it?" Before I said anything one of his teammates said "Obviously." then he yelled at the guy who made the hit something about "Play smarter than that." The guy who was flagged got up, smacked his own head, then held out his hand to the ball carrier and said something that I took as an apology because they dapped hands. I thought the video would show it clear as day, but it didn't. On video, it was hard to tell if they even touched. Funny how that works.
