Which will in turn make Czech "THROW IT UP, BIG MAN!".
Czech, if you had simply said that you disagree on the issue instead of insisting that they were wrong, maybe she wouldn't have gotten as mad. The way you said it might have sounded like you didn't respect their beliefs. But I'm sure you realized that already.
I used the TSM style of rebuttal: quotation-wisecrack. That doesn't go over well outside of TSM. I found this out the hard way.
And I didn't insist they were wrong, I just did what my teachers taught me to do: argue my point with the belief that I'm correct.
