UK to leave EU

[DLJ]

Now let's break down the word Islamophobia. It means irrational fear of Islam.

In fact, the word is used most commonly, colloquially to mean 'bigotry towards muslims'. Yes, it has a root definition as you've described but you can't ignore common usage simply to fit your belief that the term is bullshit.

Sure, the term has been successfully claimed by the regressive (authoritarian) left but that does not mean it can't be reclaimed. 

 Failing that, there needs to be a counter-meme that establishes a new term that means "rational fear of a Caliphate" or some such (although, thinking about it, can one have a rational fear? ... It would be like having a rational passion or a rational love    ).

Try it.

If anyone accuses you of being Islamophobic say "No!  I'm Caliphophobic.

Spread the meme... GO!
