If you say it that way, then yes, even the nicest person will call you a cunt and fire you. If you ask questions, as a user, and showing patterns that support your thesis, this becomes a conversation, rather than a “do it that way”.
edit: People are not all knowing. Once you start asking the right questions, you’ll see that - “Ok, and what happens when the user presses this? And what happens if they delete that?” It’s obviously a very abstract example, but if their ideas can’t stand a single user test, then they shouldn’t be surprised if the feature flops.
