You don't seem to understand the difference between a general point and being "vague", hence your obsession with demanding people jump through your arbitrary hoops and spend their time establishing some pointless technical credential instead of actually engaging with what they said. You do it in every thread to pretty much every poster.
Then when people don't dance to your command you think it reflects badly on them rather than you not being particularly interesting to converse with due to the fact 90% of your replies are grandstanding or issuing some tangential challenge about a technicality rather than replying to the general point made.
If you think quoting a scholar on an internet forum, while adding minimal commentary and not arguing for any definitive conclusion constitutes "posing as an expert" then knock yourself out. Whatever floats your boat and all that.
You might want to try taking yourself a bit less seriously though, it's a forum: an entertainment medium
Let's say I asked you to read my posts properly and reply to them based on what I said. Could you do that?
If you didn't insist on dancing around so much you might understand things better and not keep barking up the wrong tree.
Given the post wasn't even addressing you, tell me what point you think I was making, in context, and what you disagree with like normal people do
before demanding is I spend my time doing what you want.
There's a good chap.
