Corrections will always be proportional to the dog. You use it when it needs it, some need none, some need some, some need lots to get the same result. The point is if you're assessing the dog and seeing it needs it and use it properly (you know, not rip its head off or beat it with a lump of wood) then I don't see why the need for BS propaganda is.
This is my life, an in part my livelyhood. I have spent a lot of time, effort and money to get where I am so I do take it a little personally when people with NO concept of what I actually do put up stupid posters like that and tar me as a bad person.
