Oh, did he delete his comment? I had simply blocked him because I have no time for people that nitpick my correct spelling of "Muslim" or "Islam", etc, when they want to spell them as "muslim" or "islam" because they fail to realize that not writing or spelling properly undermines their arguments. They look like uneducated fools and therefore, no one is going to listen to them or take them seriously.
I've had to block several people on Twitter (when I had a Twitter account which I don't even miss), Facebook, etc. for being more interested in word games than in the substance of my comments or arguments and they tend to be irrational, intellectually stunted, and emotionally unstable people, so the sooner they are blocked the better.
They can keep their free speech, of course, and I'll keep my right to ignore them or to remove them from my daily life by not having to read any of the rubbish they spew.
