This type of response is off topic, and seems postured at a more personal level. A simple PM addressing your concerns would seem more appropiate in maintaing the integrity of the thread.
Thread "drifting" is probably one of the most confusing and time consuming " learn nothing " efforts,( other than entertainment ) (?), and as such, are educationally disruptive.
Please feel free to PM me with any of your concerns.
