So it's only skill if the weapons recoil like an idiot...?
Doesn't that make it much harder to excel?
Recoil in cs meant that you had to aim before you shoot (until css and cs go came along with reduced recoil, hence why much of the cs community doesn't like those games).
You had to make your shots count, and the self control aspect of the game (you needed to wait for the spread to reset before firing again, but not too long or you die yourself) was an entire meta game.
It's immensely rewarding and adds another layer onto the skill cap and learning curve.
It's something cod players will never know and will miss out on, their loss.
It doesn't really matter how you add layers to gameplay and the learning curve, it can be recoil and sound (cs) , it can be movespeed modifiers through strafejumping (quake), it can be non-hitscan weapons (quake and ut and especially tribes), it can be movespeed modifier through skiing (tribes).
COD (nor any of the modern third person shooters) doesn't have those extra layers, it is a shallow game with a very limited learning curve and very low skillcap.
That is why it is looked down upon by competitive players and why many people don't take esports seriously.
This is all super off topic btw

Kids act like little cunts in cod because the game is designed around gambling mechanics, denying , randomness and chasing carrots. It has a very high frustration factor but the gambling mechanics/carrots keep people chasing where they would normally stop.
This escalates into the kind of behavior you see in these videos and that you hear over xbox live.
I feel sorry for anyone who plays something that has so little to offer yet can frustrate them so much all to chase base instincts.
