This question is trying to get some clarification for why Are there in-universe reasons reason why Dany wouldn't start her conquest in Dorne? would have been closed.
Here's the actual question:
Any possible reason why Dany will not start her conquest of Westeros in Dorne?
To me that sounds like the OP is really asking a yes/no type of question. "Should Dany start her conquest of Westeros in Dorne?" While we can't answer whether or not Dany will start her conquest in Dorne, I believe it is possible to answer this question by presenting the currently known issues with a Dorne Invasion and letting the OP infer the answer based on that.
From my understanding, this question was put on hold as opinion based with the argument that multiple factors that lead to the same answer make a question unanswerable.
From my reading of What are the good ways of avoiding a "promotes a pet theory" question?, this should be considered on topic as asking for backup for a theory is considered on topic.
Is this correct? Is a question too broad if there are multiple lines of reasoning to get to the same answer?
