It absolutely is the issue, and if you are going to tell people that they need eye exams, then I am going to tell you that you need to re-read and learn the rule. If he intentionally raised his leg to make contact with the puck and then it went into the net, it is no goal. Period.
It doesn't matter if he didn't propel the puck into the net. A distinct kicking motion is irrelevant. You can only intentionally redirect a puck in with your stick.
Sorry, you are just wrong on this.
