Well, if he is Blake and he has a masters in science then he can just develop a “think to type” interface rather than using a keyboard like the idiots on AF.
I think one of the key points that Brain and BS are missing is this: there is no “ad hominem” argument here. An “ad hominem” fallacy, in the typical sense, is rejecting an argument on the basis of some irrelevant fact about the author. EG - saying, “John Doe says X. But John Doe has an ugly girlfriend, so he must be wrong.”
In the OP, however, the argument is Blake himself, not some statement that he has made. The only way you could make an ad hominem attack is on the person stating the argument (in this case, me). Don’t confuse an insult with an ad hominem argument.
I believe it was a thread discussing software. Bchad typed something, then Blake replied by stating that Bchad was the most useless poster here and that his posts were a waste of space. A side of Bchad we’ve never seen then emerged and it was game on. All this while 95% of AF was asleep as it was a few hours before dawn eastern time.
