that entire colonialism thing

Not entirely sure what you meant with this short remark. I oppose colonialism for the same reason I oppose people who impose their belief on others. Because I support each and everyone's human rights.

Go burn Bibles in public, then… we’ll see how long it takes the christo-fascists to show up at your door. Somehow, I don’t think you will.

Can you point me to any incident in the past where burnt bibles lead to angry mobs, setting buildings on fire or killing people? I'm not aware this exists. If that was a thing, I would fully support burning bibles, although I'm personally not.

willing to run interference for these nazis - as long as they can be aimed at Muslims

I understand your concern but I'm not in that camp, on the contrary. There are more sides to this story. There is a significant overlap between the reasons for me being antifascist and the reasons for opposing imposing beliefs.

You could be right in this case, we don't know.
