Conversely, has anyone managed to change your mind here in this thread?
Probably not...
The point of good argument isn't to convince the other party they are woefully wrong and everyone should just eventually come to the same conclusion.
Some debate for sport/fun, others to make a point. In the end a good debate serves to strengthen one's own ideals via plugging of logic holes poked by the opposite party. Occasionally someone may change their viewpoint -- but only someone with a very strong ego would believe their sole argument was so compelling...
If you surround yourself in an echo chamber, it's easy to believe your viewpoint is the only correct one.
