This website is using the Discourse commenting system, which allows anyone to comment on posts using their social logins.
However, I have some guidelines when posting comments. I'll remove any comments that don't adhere to them.
Basically, play nice.
Sure, criticize away. Object. Put forward an argument or counter-argument, but getting personal and childish doesn't cut it.
There's no room in the world for such antics and so comments like that will be removed.
