@OmSigDAVID,
Being an engineer has nothing to do with having the capacity to utilize common sense nor does it demonstrate an ability to critically think. There are plenty of physicians and nurses I know that measure patient medication and utilize complex medical instruments who lack common sense or intellectual autonomy. Most of them often forget to pay attention to detail and the fact that he has demonstrated a lack of intellectual ability here on a mere sports discussion says nothing about whether he was a retired successful engineer.
Anyone on the internet can be an engineer. I could be an astronaut. These are mere words but how he has demonstrated himself here, whatever he has said is suspect. As far as your comment:
"Can ignorance be forceful?"
Yes. If a racist person is presented with evidence that all Homo Sapiens are descend from the Homo Erectus who originated in Africa, and the racist willfully denies this claim despite insurmountable evidence, that is forcing oneself to ignore factual claims despite those claims being substantiated by factual and objective evidence. So in this case, if I challenge BillRM's notion that the slogan "no justice, no peace" and I substantiate my claim that it refers to a Biblical passage and that the philosophy behind that has some sort of spiritual/social context to it yet he refrains from actually looking at it and continues with his own bias that is willful ignorance and outright stupid.
It's about ignoring factual claims that contradict a person's beliefs. If someone ignores the basic mathematical principle that 2+2=4 and continues to believe that 2+2=5 that is not only ignorant but its also stupid because universally most people comprehend that 2+2=4. A 10 month old baby is ignorant of that fact because a baby is absent of any mathematical foundation. BillRM is a grown ass man who knows that every African American marriages are not related to this subject. He also knows that Jesse Jackson does not speak for all African-Americans as case in point, me being part of the all I've told him several times now he doesn't speak for me.
BillRM knows that all blacks are not violent (if such were the case he wouldn't have made it known he has bi-racial kids in his family). Yet if one maintains that a particular group is hostile despite the overwhelming evidence that is opposite of that then yes you deserve to be called stupid. It's one thing to be without knowledge, its another to know a thing but refuse to accept that truth.
