African Terayza said "OUR forefathers...."
She's phony as the proverbial $3 bill.
And it doesn't take exceptional discernment for a leftist to realize that when she starts throwing around words like that, words like "un-American," conservatives are going to home in on that. A leftist calling others "un-American" is like Porky Pig telling Stephen Hawkings that he talks funny. People like TerAYzah are the epitome of un-Americanism and McNickle, like any conservative, was not going to let her slide by on this.
As I said before, her best option was to deflect his question, eg. "Well, by 'un-American,' I meant 'not characteristic of Americans,'" which would essentially have been deflection by redundancy. That would have saved her, even if McNickle's follow-up had been, "So which Americans are doing this Un-American activity?" She could have simply said, "I don't think it's constructive to get into personalities here," and just walked away.
But by responding the way she did, she just compounded her embarassment while presenting us all with the absurd spectacle of a leftist accusing others of un-American activities.
