Flinch on sniper rifles, why is it so low?

I mean, they are looking through scopes that zoom in 8x or something like that and the flinch they get seems to be exactly the same that you get with regular guns without any scope. I know CoD isn't supposed to be a simulator but it is still meant to be somewhat realistic.

Combine that with Toughness (which basically for the first time is a viable choice in a CoD game and a very popular one at that, espescially for snipers) and you can shoot very accurately with a sniper while being shot by a silenced SMG at range for example which requires like 5 to 6 shots or something. To me that is really stupid.

If you don't understand what I'm talking about, imagine you're watching through binoculars (sniper scope) and someone pokes at them, you're vision is going to wobble quite a lot, and then do the same with just regular glasses or something (regular gun) and it's going to be considerably less. Pretty bad example but whatever.

What is your experience with this in Black Ops 2?
