Why do casuals act as if it's the end of the world when suggesting?

FFXIV is often described as a "theme park mmo" where you can do what you want.

Not to be that guy, but an MMO where you can do what you want would actually be a sandbox MMO. A theme park MMO, like WoW, FFXIV, GW2 is an MMO with pre-built "rides" such as quests, dungeons, raids, and other events designed by the devs for players to experience in a guided manner. In a sandbox MMO, like EVE Online, I can choose to be a bounty hunter and kill players/npcs that are criminals anywhere, anytime without being prompted by a quest or a special event.
