Cumorah and population numbers

Some critics claim that the Book of Mormon account is not credible or even feasible because there could not possibly be an ancient war at Cumorah that killed 2 million people, let along 2 million men along with their families.

It's a fake objection because the text never says or implies anything of the sort.
