I thought "eristic" meant a love to debate. Most of the people on the Off-Topics seem to just want to post videos or copy'n'paste articles from elsewhere or people's twitter feeds, or quoting other posters copying other people's twitter feeds. I don't see much debate.
Yes, we get a sometimes provocative thread title and then see a video that's 47 minutes long without a bit of introduction. Common courtesy (I know, what's that any more) would suggest a little primer or something, but no. We're supposed to have the time to go cold turkey that might turn out to be a bust. One poster in particular does what you mention above almost exclusively, I'm not sure whether he/she can even write. Non-stop bashing with no verbal give and take.
