Qualified? Simple observation could determine that. You would be the least qualified since your angry emotions are clouding your rational thinking and self-assessment.
I was on this board years ago, and now that I visit again, it's still the same thing, always the few like you who are incapable of taking any opposing view without getting angry. I've seen your posts in different threads. You are incapable of handling any opposing view without taking it personal, thus you become emotional while rational thinking is thrown out the window.
It's been discussed in threads of the past, how to spot those whose emotions control them. Anger, cursing, personal attacks, etc. Same indicators, nothing new. They are those who are too fragile to face any opposing view and simply debate objectively and without emotion.
And your "fuck off" response is certainly adding value.
