Poor example.
Not removing a screaming baby/child from a restaurant is just as rude.
Have the baby start crying halfway theough Small World...well, then te parentms options areore limited.
My point wasn't about how the parents should react to the screaming baby. Only that a baby, like some individuals with special needs, cannot control their actions, nor can they appreciate how their actions cause others to react.
But by extension of your response, would you expect the parents or guardians to remove an individual with special needs just because their behavior is annoying to you? Or maybe neither the baby or person with special needs should be brought in the first place due to the possibility of their behavior annoying your or others?
The reason people bring up the possibility of people having special needs is to allow the rest of us to be aware of the possibility that our assumptions may be incorrect. It is not to discount the OP's original point about otherwise rude people.
