Paigntonian - // Plagues were caused by churchgoers? Even if it was correct, which it is not, it doesn't address yesterday's events. //
You are right, plagues were indeed not caused by church goers, that is not correct.
But that is not what Atheist said.
What he said, was, and feel free to re-read his post to confirm it -
// ... but many plagues were spread by misguided believers gathering in churches thinking that god would protect them. //
And that statement is correct.
If you are going to have a pop at someone for something they said, be careful to make sure that it actually is what they said, and not what you think they said, and then criticise them for that.
It makes you look rather foolish, and lines you up to apologise for your unwarrented crticisim.
