Argument by dismissal and hand waving at your opponent is generally how you left wing people debate.

No, its not. See, e.g., most of my post history.

Sometimes, OTOH, completely moronic ideas are offered without any support, and without it, contradiction is all they warrant.

I won't debate any further with someone who resorts to name-calling or dismissive language. You didn't provide a proof of contradiction or any argument. I provided valid reasons and evidence to support my point of view.

> I won't debate any further

You weren't debating before, just posting unsupported conclusions with no argument in support, and complaining about responses in kind.

You're right, but you are being pretty harsh and insulting, and it does distract from your point and make it just about impossible for the other commenter to hear what you're saying.
