Hi,
Author here. I'm glad there are people like you who share the same view. :)
I do admit that I haven't explained things well in my blog post, but some comments here that suggest being aggressive/rude is okay and/or justifiable as long as there's another side of the story is really an eye opener for me and I'm somewhat shocked... Is being kind and decent to another fellow coworker (and a human being for that matter) too much to ask? :\
