If you seek genuine debate with Mormons, it can easily be done in good faith, and without making an ass of yourself, or needlessly driving a wedge.
Do not bog yourself down into pointless and stupid hostilities. The driving force of this recent phenomenon is by third worlders seeking to exacerbate divisions between heritage Americans.
Whatever you believe or think about them, whatever differences you may have, they settled the hot, hostile, and hard lands of the Comanche, the most vicious, cruel, and relentlessly homicidal of the Indian tribes. They arrived on little more than hopes and prayers, said "this is the place", and transformed it into a paradise.
They are true Americans, and patriots.
We are fast approaching a time where the rest of the world will be at our throats, and come whatever may be necessary to restore America to her former glory and beyond, we will absolutely need to rely upon one another.
I held a poll recently to ask a simple question; would you rather have White Mormons as your neighbors, or minorities of your own denomination, and the answer overwhelmingly, almost unanimously, displayed a preference for the Mormons.
Debate whatever you wish,
But you ought to reflect upon that.
