He has no clue about how hot and detailed the disagreements here can become, nor did he care to find out. A lack of curiosity is a poor trait for anyone in journalism.

Keep us posted as to whether he has the guts to invite you to his new media symposium. It will give at least a preliminary indication as to whether he is serious about trying to understand the new media.
