In case you have comprehension problems, let me repeat:

"As for printed signs and organization,"

The pro-Saddam aspect of the so-called "anti-war" marchers was shown by their refusal to have those Iraqis who were protesting Saddam to be allowed to join them. I posted the article years ago, giving the names, place, and dates ( London, I think).

Since they did NOT tell Saddam to comply, ( and avoid war) it is obvious they were NOT anti-war, just anti-US action.
