Comment 17 by esuther :

Not being able to remain silent (a common writer’s weakness) I confront some woo peddler or other almost every day, and my comment often elicits an entire dispute. Even if it begins in a civil way, which is about half the time, the discussion soon becomes soured by the believer’s sense of outrage.

LOL, I do this all the time on completely unrelated gaming forums(in off-topic subforums or if someone brings something up in other subforums) and such. Glad to see I'm not the only one.

The worst thing atheists can do online is exclusively comment on atheist blogs, websites and youtube channels. Many atheists don't even realize how pointless this virtual ghettoization is. The worst example being PZ Myers' blog with hundreds of comments, just imagine if that effort was put on mainstream websites and articles.

Basic common sense.
