To be honest, I do see humour in most things but have the "common sense" to realise that, in some cases, others may not. As the subject had only arisen through someone pointing out that they'd found it offensive, it seemed a little bit stupid to rub it in.
Ultimately, we all have the ability to ignore things we don't like ( which generally I do), but you annoyed me with that post and felt the need to respond. Hopefully you won't encounter circumstances that you lead you to be "over sensitive".
