Excellent!!
You are wrong, btw! Conflict is essential to progress. I am not going to back this statement up with anything, but just present it as an assertion.

Games are fun, I generally enjoy them. What are interactions with other people if not games? In which we are never quite sure what the response will be, but can amuse ourself with trying to predict it, amaze at how right or wrong we were. I don't see what makes the empassioned debate, aka 'flamewar', different than other exchanges. Often people are just so unfortunatelly squeemish about disagreement, especially when it seems to be over a fundamental point. I think this is in particular important for the left, to disagree on things each party feel important, to yell and fight about it, and to still carry on a strategic allience with mutual respect despite or because or unrelated to the disagreement. Crucially, it is respect for the person, not for his/her opinions, which one might occasionally find daft.

(Didn't see the video, I don't think the computer I am on can handle such fancy modern wonders.)
