Is this thread for real?
I have no problem sitting next to an UM provided the UM behaves itself and doesn't upset me. The moment it does upset me I call a member of the cabin crew and tell them to deal with it.
What is wrong with that?

I think you've misunderstood this thread. No one is objecting to sitting next to a youngster, but some (including me who as a single chap that sometimes flies alone) object to assumptions being made that we are somehow a threat to a child travelling on their own.
That's bad enough, but if a member of the cabin crew loudly insists that you move (as happened to Mr Fischer who was sitting next to a child he did not know) then I think we have a right to feel aggrieved.
