Theo 1689
There's something called a "red herring" fallacy. It's when someone wishes to dodge a topic by throwing out something completely unrelated, hoping people will be more interested in following that thought than in actually engaging the actual topic, in just the same way that an escaped fugitive might throw out a "red herring" to try to confuse the tracking dogs, and getting them off the scent. "Calvinism" is just one of many "red herrings" Mormons throw around to try to avoid actually defending their own beliefs.
And that's the point in that other thread.
Mormonism gets challenged, and Mormons throw out "But Calvinism!", as if that solves anything. But there are those such as Martureo, who don't believe in Calvinism, and so your red herring demonstrates nothing, and the challenge to Mormonism remains undefended.
And then Mormonism gets challenged again, and Mormons throw out, "But the Trinity!", as if that solves anything. But there are those such as atheists, Muslims, and Jehovah's Witnesses, who reject the Trinity but still know that Mormonism is wrong, and so your red herring demonstrates nothing, and the challenge to Mormonism remains undefended.
--------------------------------------
That's why we constantly bring up two constant truisms:
1) Mormons have no defense of Mormonism against atheism, since they need another religion to "counterattack", as a red herring;
2) Attacking another religion doesn't make Mormonism true.
