Nope. The concept being discussed was obviously the concept that you were implying I didn't have the critical thinking capability to understand. All other concepts are irrelevant.
If not, what objective standard are you using to define it an 'insult' to point that out?
The standard that it is rude to point out a perceived deficiency in someone that doesn't concern you directly and without offering something constructive to help them overcome that deficiency.
OK, so far so good.
"The concept being discussed was obviously the concept that you were implying I didn't have the critical thinking capability to understand. All other concepts are irrelevant."
You have already admitted that there are concepts that are beyond your critical-thinking ability.
"The standard that it is rude to point out a perceived deficiency in someone that doesn't concern you directly and without offering something constructive to help them overcome that deficiency."
I asked for an objective standard, you supplied a subjective one. If you believe that gravity doesn't apply to you in a particular instance and I point out that it does, how is that not constructive?
