Those who say that Lincoln fought the Civil War to bring an end to slavery find themselves using an argument similar to those who compare Lincoln to Lenin.

Interesting. It is only lost causers who bother with either "argument". Most people know better.

“argument”

‘Argument’ is a conventional term in both debate and logic, no quotation marks needed. It has a different meaning than the combative sense found in your writing.
