Graham's Hierarchy of Disagreement applies here. You couldn't refute the central point of something you disagreed with, so you resorted to sarcasm and mockery. Perhaps it would've helped if you had a proper counterargument based on facts and reason. Maybe you could have encouraged us to see things the way you do, but the comment you just wrote will only serve to nudge us to disagree more strongly with you.
