Objective & Subjective, but always Respective of the Collective
Islam isn’t a cult last I checked (unlike Druze which is a cult of Islam, similar to how Mormanism and Jehovah Witnesses are considered cults of Orthodox Christianity). Either way last I checked the purpose of most faiths/philosophies to spread. Instead of insulting a rival viewpoint, perhaps he should simply do a better job presenting his? Just my two cents.
