The "rules are rules" crowd also completely misses the point of why the rule exists in the first place, which is to prevent the attacking team from gaining a competitive advantage. If the alleged offside is so miniscule and happens so quickly that it cannot be seen by the naked eye in real time, then it is irrelevant and no advantage was gained by the attacking team.
Half the time when these goals get called back, the guy whose skate was a millimeter offside isn't even involved in the play in any capacity. There was a goal called back in the playoffs because a guy was going to the bench for a change and his skate was over the line. To me, that's just as bad as the time Matt Duchene or whoever the f*** was 15 feet offside on a breakaway but it wasn't called. The league WILDLY overreacted to a bizarre outlier of a play, and in doing so created a bad rule that actively makes the game worse.
