I've never been a fan of the term "moderate" to describe religious adherents, I think it's much better to categorize them as consistent or inconsistent. Currently, Islam is more of an existential threat to rational people because its practitioners are more consistent and take religion's importance more seriously than do Christians and others. An article at PJM by Andrew McCarthy does a good job of showing how ridiculous it is to give Islamists a pass for being moderates.
(a) Not all Islamic supremacists (or “Islamists”) are violent, but the goal of all Islamic supremacists is the same: to coerce the acceptance of sharia. The methods of pursuing that goal vary: sometimes terrorism is used, sometimes non-violent avenues are exploited — meaning, Islamic supremacists co-opt legal processes, the media, educational institutions, and/or government agencies. But regardless of what methods an Islamic supremacist uses, his goal never changes: He aims to implement sharia. In Islamic supremacist ideology, sharia is regarded as the mandatory, non-negotiable foundation that must be laid before a society can be Islamized. Sharia is not “moderate”; therefore, you are not a “moderate” if you want it, no matter what method you use to implement it. For example, if you are an Islamic supremacist and you want to repeal the First Amendment in order to prohibit speech that casts Islam in a negative light, you are not a “moderate” — even if you wouldn’t blow up buildings to press your point.
(b) Islamic supremacism is not a fringe interpretation of Islam. It is probably still the minority interpretation in North America. Nevertheless, it is the predominant interpretation of Islam in the Middle East. Poll after poll shows us that upwards of two-thirds of Muslims in countries like Egypt and Pakistan want their governments to adopt and strictly enforce sharia. This is why the Islamic supremacist parties in the “Arab Spring” countries are currently enjoying such success in electionsHe then goes on to show how we whitewash the threat of Islam, even denying the common underlying motivation that these killers have:
The Obama administration and the Republican establishment would have us live a lie — a lie that endangers our liberties and our security. The lie is this: There is a difference between mainstream Islamic ideology and what they call “violent extremism.”
The vogue term “violent extremism” is chosen very deliberately. To be sure, we’ve always bent over backwards to be politically correct. Until Obama came to power, we used to use terms like “violent jihadism” or “Islamic extremism” in order to make sure everyone knew that we were not condemning all of Islam, that we were distinguishing Muslim terrorists from other Muslims. (In a more sensible time, we did not say “German Nazis” — we said “Germans” or “Nazis” and put the burden on non-Nazi Germans, rather than on ourselves, to separate themselves from the aggressors.) But now, the Obama administration and the Republican establishment prefer to say “violent extremism” because this term has no hint of Islam.Be sure to read the whole thing.
