"If you disagree with me, you're wrong." Wonderful argument.
My takeaway from "If you don't believe this, I suggest you carefully reexamine your assumptions." is "If you believe something is true, stop and think critically about _why_ you think it's true. Be open to the fact that this process may lead you discover it isn't true after all".
If OP wants to make a convincing point, the proper way is to propose a convincing argument, not "Think about how you're wrong."
