I didn't say you did.
And...yes. That's sort of how it's always been, at least in my recollection. I've never actually seen a goal called back after a stopped player merely angles his skate - there's almost always a little bit of force put behind it as well / a slight leg movement to direct it towards the goal along with the re-angling, which instantly makes it a kicking motion. But I'm quite certain goals that involve a player skating and redirecting the angle of his skate without really deliberately changing up the speed / motion of his leg in the process have been allowed. It might be a bit of a grey area, but generally speaking I think what's a kick and what's not is fairly clear most of the time. To me at least what Hornqvist did was allowable.
