The argument against ridicule

Loftus completely ignores my argument for what I said, which has to do with the principle of charity. An argument for something, if it is done right, does the best it can to state the other side's position as fairly as possible, and to even to make a better case for the opposing view than even its advocates make before launching the attack against it.

The Principle of Charity is a methodological presumption made in seeking to understand a point of view whereby we seek to understand that view in its strongest, most persuasive form before subjecting the view to evaluation.

Ridicule, on the other hand, seeks to present the opposing view in the most negative light possible before attacking it. How can you be charitable and ridicule at the same time?
