should we be happy about trollpicks?

I am seeing it again and again, someone will trollpick and a player is forced to go some where else than he called with a champion that does not suit that role. Now i am just wondering why the other players mostly the person that trollpicked thinks that since you where forced or bullyed from your lane you should be happy? and not displeased about it. I even saw a player trollpick ADC and say to the person that had called adc and was not happy about being forced to go support " You should be pleased that I let you supp me!" why in the seven hells do you think that just becouse that person did whats best for the team he should be happy about it?
