You haven't been putting in any good-faith effort into having a "productive conversation" for at least three of your responses, setting up "This is how things are" with no attempt to support this with any arguments, and have equally refused/dodged out of engaging with any of mine.

Your brain has just had your mental block up very obviously starting from your knee-jerk "what is wrong with you?" comment, isolating you from the scary prospect of being convinced by a consistent chain of logic, and now you're looking for a face-saving way of ejecting from the conversation.
