Here's how it went:

1. In a thread about the Georgia election [!], the original poster raised the prospect of "pro-democrat aliens outbreed[ing] the traditional voters."  You'll have to ask him why.

2. My response to him was a one-liner poking fun at his "fear of aliens."

3. Then Martel brought up the "the "Canadian" at the Flint Michigan airport."  because that's what a guy who names himself after an 8th century AD anti-muslim warrior does. I answered him back, and then you got into it.
 

So if you're looking for the kind of guy who sits in his basement seething with resentment ... you know where to look.
