Depends on how you define expert. Somethings maybe, many things no. When I am not an expert I don't make such certain claims because I know there may be a lot I do not know.
You realize you just said you were an expert in "some things" [sic], but didn't bother to offer what you think "expert" means?
Everything depends on how you define things. Maybe using the generally accepted definition is a reasonable starting point.
Why would you ask ME if I'm an expert on this topic, when you have no definitive opinion on what that even means?
This is why these threads go around and around. Plain English still exists. It's not hard to use, but if something can have multiple meanings, and it's not clear which you are using via the context, it's customary to let the reader/listener know which definition you are using.
But, I'm not an expert in English, meaning i've never been tested against any "expert" standard or earned any credentials such as a teacher or professor, linguist or similar. However, i did ace the standardized English competency test my Freshman year of college, so I didn't have to go to that class for half a semester. Oh, and i received a commendation at the US Air Force Squadron Officers' School at Keesler AFB for outstanding written communication. Maybe that qualifies me as an expert in English?
i don't have any credentials in the topic of psychopaths or what "unique motivations"
almost school shooters may or may not be experiencing. But, I have lived a long time, been to a lot of places, seen all kinds of people, and experienced people with mental issues, emotional problems and even those who committed horrible crimes. Some might say that gives a person "street creds", which I've often seen outweigh purely academic information which was memorized and many times regurgitated without assimilation.
My ex has a double major in psychology and sociology. Even with that degree, I was still better at analyzing what people are going through, why they do what they do, and how to best solve a situation involving some pretty difficult and dangerous behaviors. Not saying that was 100% of the time, but I've been told by many I'm have a knack for reading people and situations, and that means my analysis and solutions are usually spot on.
Expert? Does someone need to be labeled an expert for you to believe the verifiable facts someone is offering you? Or is this just your last ditch attempt to discredit my opinions since you've run out of arguments?
When you can't win on the facts, attack the person.
