@Gheritt, A few years back, when I was criticising the quality of Sony's first part releases at the time - God of War 3 being one offender - I was constantly accused of being an Xbot. (despite owning a PS3 and PSP)
When I began criticising Microsoft's bad management of their studios, as well as their restrictive rules in place for devs on Xbox Live, I was suddenly a Sony fanboy with a format bias. (despite most multiformat gaming being done on my Xbox)
When I felt like the Wii U was being unfairly criticised for its underwhelming hardware specs and that it was irrelevant to good game design, I was branded as a Nintendo apologist for months.
The point I'm making is... insulting a person's character is a cheap and easy way to avoid critical thinking. Why engage in discourse about differences in opinion when you can just insult the worth of someone's opinion instead? Many people find it hard to look at their own opinions in any critical perspective.
There can't possibly be another viewpoint than your own.
It clearly must be the fault of other person, right?
Obviously if they don't agree they must be ignorant.
Trying to invalidate someone's opinion by undermining who they are is one of the easiest cop outs. Sadly, its also one of the easiest. If there's thing I've learned from over a decade of discussion on the Internet its that when someone starts resorting to personal insults to argue their points, the discussion is already as good as done with.
