Of course I have a problem with political religion,

I gathered that you have, but I don't know why ("of course" is no explanation).

JakeS:

You're the one who is advancing the notion that partisan religious politicking must represent a cohesive, almost conspiratorical, political movement.

No, but if you argue that there is a coherent thing as "political Islam", then you must prove that there is a coherent movement. Especially (but not only) because you are not in a political vacuum, but surrounded by voices that talk of "political Islam", "Eurabia" and the like. You want to say something else than they do? Then make that clear.

Even then you are wrong: there are attempts to use religion (in this case Islamic religion) arguing different political points. It is lazy to claim all these points were the same and it is lazy not to argue the political points but the religious angle advancing them.

JakeS:

Politicizing the pulpit is an authoritarian persuasion strategy that uses appeals to in-group identity to advance whatever garbage the preacher cannot advance by honest means.

Such as the following I assume. "People often speak of God being even-handed. God is not even-handed. God is biased in favour of the weak, of the despised."

There are of course many ways to make above point, not only the theological one, but I don't think any of these ways is dishonest. Are you sure that you object to politicising the pulpit in general, or is it certain political aims you object to?

JakeS:

Most of the garbage being peddled also happens to be reactionary garbage.

Possibly. No idea. Have you no arguments to argue against reactionary garbage then, only against the channel used to transport it??

So far I have treated the points where you are only wrong, but nothing worse.

Additionally there are two other issues. All these anti-Muslim campaigns target a community that is discriminated, poorer, less educated, without equal chances on job market, market for flats and so on. It is spied upon, its members are targeted by "security" services as collectively suspect. At the same time this group is victim of hate crimes, murders, arson of mosques and so on. And you find it perfectly okay to take their religion on top of that and ridicule it, humiliating the people who believe in it. I resent this inhumanity in its own right AND because it is another de-solidarisation. There is nothing leftist in supporting an alienation of these people.
