when I first started goign to playgroup I would get offended if someone pulled jack up like that but now I have been going for 6mths or so I feel more at ease with it, as long as no-one lays a hand on jack I am fine if someone pulls him up, I even now will pull other kids up it did take me a while though, the other week I had to physically pull a child off Jack but those occasions are rare

I think just leave it...
