You didn't read PH's note at the top of thread
did you?

I most certainly did. Ignorance is not necessarily a bad thing, and it can be rectified. It is also verifiable. Therefore, mentioning one's ignorance cannot be an ad hominem as there is hard-and-fast data, and not just an opinion.

Note, ignorance != stupidity. If I had used the latter, you would be justified in citing an ad hominem attack. However, I do not consider you stupid, simply willfully ignorant.
