once a wise man said that whenever you send a mail to a customer you should never include more than one question in the mail. Otherwise, the mail will only answer one question and leave the other unanswered.
SE kinda works the same: when you write a question, whenever excuse that could be used to downvote/close it will be used
That's kinda a Catch-22 situation in some cases... You are free to express any form of disagreement on meta but disagreement = rant = close
