It's always possible, if a person wants to take the time, to disagree with an idea without resorting to childish, insulting ridicule. Ridicule is ineffective. Ridicule is only enjoyable to those who engage in it. If Simon did not allow it, which in my opinion, he should not, you wouldn't be standing up for the practice. Because he does allow it, you feel emboldened. That doesn't make the ridicule anymore effective. It does on the other hand, show the true colors of those who engage in it. Anyone, including me, can slip and do it, because it is human weakness to ridicule. To the defend the practice as an effective communication tool, shows a lack of growth and maturity, when it comes to expressing your core beliefs.
