Walker, I realise that as a writer you should stand up for what you believe, but I think now would be a good time to drop the argument. It's clear that you have caused a great deal of offence which means that no amount of point and counterpoint will change the general feeling.
I guess Swerytd offers up a most fitting critique of your work and personally, in my opinion, it would be in your best interest to take in what he has been written, agree to disagree, and back down gracefully.
