It is not an issue for me either Dave, but I will condemn it.
It is unpleasant, unnecessary and is likely to discourage participation and debate.

Musket, I called you a liar when you claimed to have heard on BBC of Christians in Nigeria attacking a Muslim school, killing children and feeding them to pigs.
Neither BBC nor any other agency has any such story reported, so you made it up.
Also, when you claimed to have downloaded a quote that Google could only find in your post, and you claimed it came from an organisation that does not exist.
