I expect him to have certain biases but I don't find it unbearable like I do with Benjamin Brooks and Matt Gemmell where I always get a sense of anger, contempt and general negativity in their writing.
It didn't bother me that he was wrong. It bothered me that he called everyone an idiot for using a stylus on an iPad. This is the kind of person who will criticize sooner than give thought. I would not want to read what he has to offer or be around him for any length of time.
This is one of many posts of his site or his Twitter account.
