My HOD at that time was a religious man and a few days after the talk, he told me that he did not like what I said. My argumentative self took over and I began to debate with him. Things got so heated that he walked away.
I have since come to know that debate (just a nice way of saying arguing) about religion is utterly futile.
As Zhuang Zi said:
既使我與若辯矣，若勝我，我不若勝，若果是也？我果非也邪？我勝若，若不吾勝，我果是也？而果非也邪？其或是也，其或非也邪？其俱是也，其俱非也邪？我與若不能相知也，則人固受其黮闇。吾誰使正之？使同乎若者正之，既與若同矣，惡能正之！使同乎我者正之，既同乎我矣，惡能正之！使異乎我與若者正之，既異乎我與若矣，惡能正之！使同乎我與若者正之，既同乎我與若矣，惡能正之！然則我與若與人俱不能相知也，而待彼也邪？
"Even if you and I argue, if you win over me, and I do not win over you, are you indeed right, and am I indeed wrong? If I win over you, and you do not win over me, am I indeed right, and are you indeed wrong? Is one of us right, or is one of us wrong? Are both of us right, or are both of us wrong? Since neither you nor I can know, others are inevitably shrouded in darkness. Whom shall I have to decide it? If I have someone who agrees with you decide it, since they already agree with you, how can they decide it? If I have someone who agrees with me decide it, since they already agree with me, how can they decide it? If I have someone who disagrees with both you and me decide it, since they already disagree with both you and me, how can they decide it? If I have someone who agrees with both you and me decide it, since they already agree with both you and me, how can they decide it? Thus, since you and I and others cannot know one another, what then shall we wait for?”
