I usually read columnists on my mobile phone, and do not get to read the comments. Today, I logged in from my computer, and scrolled down to see the comments left by other readers. The same trolls left the same worthless incoherent posts on nearly every article. This is really sad. I used to read the thoughtful, thought provoking comments encouraging critical thinking and debate. Now, not really here anymore. The worst today are from "Troglidite", "crude", "q16penn", and "Henry III"- if the same drivel is reposted on every single column, where is the thoughtful debate about the article? Please work to remove this type of spam.
