Sorry but you went beyond disagreement. Here is Deep 1 post again....
"I'm not posting as a Mod but as a regular poster. The image is disturbing, no doubt, but Archaic has not violated any policies in posting it. Sometimes people need to see a picture that is worth a thousand words. The active Mods have done the right thing by providing a warning for graphic content instead of the picture being automatically displayed.
However, calling for a ban on a poster for a pic that some people may be squeamish about is over the top. Chill."
I think there were two main points in Deep 1's post you believed were wrong? 1. The poster didn't violate any policies in posting the image. 2. Calling for a ban is over the top.
Here's why. Here is your post.
"This is yet again another topic about a terrorist attack from a poster with a history of conflating and soapboxing on the issue of Radical Muslim terrorist attacks, immigration and the practice of Islam."
Here you telling Deep 1, no, he has violated policy because this is another Islam topic from a POSTER with a history of soap-boxing and conflating. You support this claim by providing the warning by a mod on this very issue. You wouldn't have provided the warning unless you believed it supported you claim.
So sorry ES you can shuck and jive,deny,spin and all but obviously this was an attempt towards having further action taken against the POSTER. Its the only reason to provide such a post and provide the mod warning.
