Why does the left ignore Islamism?

Noticed how so many on the left are, understandably, pleased about the imminent downfall of the Mubarak dictatorship in Egypt, but completely nonchalant about whether it becomes an Islamist dictatorship?

How the rhetoric and thinking, almost childlike in its simplicity goes like this:

What government does Egypt have? A dictatorship

Where does most of Egypt's aid come from? US government. 

That means the US supports dictatorship.  Dictatorship is bad.

What should Egyptian have? Democracy, like "we" in the West have.  Egyptians deserve the same rights we do.

Do you believe in human rights?  Yes

Do you believe women, gay and lesbian people, ethnic minorities and religious minorities deserve equal rights to everyone else? Yes

OK so far but then...

Does it matter who gets elected? Up to Egyptians.

Does it matter if Islamists arm and fund terrorists to wage war against Israel? Silent (but we think Israel deserves it).

Does it matter if Islamists arm and fund terrorists to wage war against the West? Yes, but it would be our fault for wars in Iraq, Afghanistan, backing Israel.  They will stop when they have justice.

Does it matter if Islamists get elected who then restrict democracy to be the same sham it was under Mubarak?  Silent

Does it matter if Islamists suppress free speech, shut down competing media, arrest protestors, use the police and army to suppress dissent?  Silent

Does it matter if Islamists execute political opponents, adulterers, rape victims, gay and lesbian people? Silent

Does it matter if Islamists institute laws and enforce laws discriminatory against women? Silent

Does it matter if Islamists get nuclear weapons? America has them, so what?

See in a blind leftwing hatred of the USA, there is a total blindspot about Islamism.  For people who apparently espouse a love for women, desire for equal rights for gay and lesbian people and who hate torture, suppression of free speech and the like, their willingness to tolerate and appease Islamism is absolutely disgusting.  

It is the mindless view that anyone who challenges those they hate (the Republican Party, Israel) are to be thought of generously.

Well no.

I want Egyptians to be free, to have free speech and an open secular society and government.  I want Egypt to progress.  On balance I do not think it will become Islamist, but the risk is there.

For those on the left, whose hatred of the Mubarak regime is so thorough they will accept any alternative, are completely betraying the beliefs they purport to hold.

Want to see why? Look at how often they criticise the regime of Bashar al-Assad of Syria. A socialist Baathist dictatorship, led by a man who got his position through hereditary succession, whose father was a warm friend of the Soviet Union, who runs a secret police and torture network that rivals Hosni Mubarak. Who has invaded Lebanon twice to overthrow liberal secular regimes that were not compliant with it.

No, you wont hear quite the same hatred of Assad as you will Mubarak, because he didn't have US support.  He had Soviet support, so he isn't as bad.  I mean he has not made peace with Israel, he has not promoted peace in Iraq and continues friendly relations with Iran, so who cares?  After all, nothing gets the left more upset that the US backing a dictatorial regime - not because it should know better, but because the US is the embodiment of what they hate.

It completely robs them of credibility.  Particularly when nobody on the political opposite is saying "save Mubarak, he's good". Nobody is saying that.  All that is being said is that Egyptians deserve the rights and freedoms we all expect.  That is consistent, because it rejects Mubarak and Islamism.

However, for some on the left Islamism is implicitly ok because American is bad.

Where do you get this sort of thought? Try here, here or here for starters.
