After awhile, all those "If you don't like [insert current topic here], then don't go to Disney" posts start to look alike to me. I don’t understand what purpose they serve other than to dismiss someone’s concerns and cut short a discussion they don’t like. I think everyone knows they have the option not to go to Disney.
No, I don't think they *all* know they have the option not to go. While some raise concerns, others are clearly raising smokescreens and demagoguery and rationalizations to give Disney a black-eye for their reasonable restrictions or to make the case those restrictions shouldn't be in place.
We can tell because they raise issues which are easily dealt with, or their reasons are not based in reality or science. They just want their way because they want their way and any really poor or transparent or not-grounded-in-reality argument will do.
Again, there are those who do have valid concerns. They're usually not the ones dismissed with "well then don't go."
