Some years ago on here, I remember somebody posting something similar to this, might have been those exact words, actually. The poster the remark had been made to, later posted to say that one of his children had tragically lost their life in a traffic accident, and that he had PTSD as a result of this. This poster made a plea for everyone to think before they post, because you never know the personal circumstances of people reading your posts.
Point being, I know the Coventry fans on here can be irritating, posting childish nonsense and cluttering up threads in which we're trying to discuss things that are important to us, but this part of your reply to one of them went too far. If they're irritating you enough to prompt you to post something like that, it's probably better to just ignore them, rather than posting something you might later regret.
