You mean he had a premonition that something in the thread will lit his fuse, and decided to lit it preemptively?
William's "lit fuse/propaganda" message was the second message in this thread, and it was an answer to the original post.

>I think you'd better re-read the post. William didn't say the original post said anything about any particular thing, he just said that some things said in the thread "lit his fuse." What does it matter if it was said in the original post or not? It was said later and that's what bothered William. You are splitting hairs over inconsequential issues when you worry about what was said in the original post.
