I'm not exactly sure who coined the word, the first time I heard it, was in an editorial by Michelle Malkin, and I was using it on the old board last year. In any event, the word aptly applies, and is an adequate descriptor to distinguish the specific enemy we face. You may call it propaganda or anything else you like, a marketing tool, or whatever... I really don't give two fucks what you pinheads want to call it, or what you think of it. The word must obviously evoke a discomfort amongst the pinhead masses, or there wouldn't be all this writhing and gnashing of teeth.
I think that is because it sort of takes away all of your false arguments, it doesn't allow you to continue to exploit the Islamic religion by classifying our enemy as "All Muslims", and it doesn't let you continue to justify and excuse terrorist activity and radical extremism. You disagree with this word, just as you disagreed with "war on terror" and "radical Islam" , so it's no surprise you protest this term as well, the problem is, this term fits well, and you find it difficult to attack and sound rational and sane.
One of these days, in the not-so-distant future, when they annually announce the new words for the Dictionary on the news, Islamofascist will be one of them.
