If moderators had done their job properly this thread would be on topic. It's been allowed to become a large blister about to pop. Dave I don't think you should waste you time on this one. I have a sense of humour but I agree with you sometimes comments can be taken the wrong way.
We like to promote free discussion here .... most threads go a little off topic - @PinballDaze is big enough to be able to get any constructive feedback from it.
Saying that, keeping on topic is always a bonus
