That’s the problem, people call people lairs with no more than their word and expect people to except their version as being right even when they provide nothing more than their opinion and then get angry because people ask for them to back up their opinion with facts.
When did it become acceptable for someone to call another a lair with no proof or facts to back their accusations? Not only do you seem to find this behavior acceptable you are almost seem proud of it.
You seem to accept this guys assertions as fact without providing any proof, other than his speculation, to back it up.
Prove that the Norks have the capability to do perform what was asserted and I'll have little problem believing it, but throw out such claims without actual facts to back it up and I call BS from the standpoint of observed actions.
Not too difficult to comprehend, and certainly not an unreasonable request.
