Not only did he insult you personally (how much more condescending can you get than "I don't think you took the time to think out your concerns"), he is self-righteous as well.
There's nothing worse than a self-righteous anti-gunner. The ones that are power hungry, you can understand and deal with. The self-righteous ones are simply ignorant and deluded enough to think that in their little fantasy world, guns really can be "ordered" out of existence. And yes, that is probably a personal insult to the author of that letter... but I would never write that to him personally.

I have to admit i thought the managers response letter was pretty professional and polite, it was the OPs letter that i found to be rude.
*silly sign- stupid idea- (not so) great wolf lodge-* etc etc.... If you dont find that stuff to be antagonistic or rude in anyway them im not sure how you feel that the response letter was insulting or innaporpriate...
