Not a point I have contested, but yet another suggestion without any sense of scale, and so far you have refused to address that aspect of five or six replies on the topic. Maybe that’s why you are inviting so much hostility?
> Maybe that’s why you are inviting so much hostility?
If you are somebody who resorts to hostility just because somebody puts forward an argument without full explanation and rationale, then you have my sympathies.
Looking at your other replies in the thread and what other people are replying to you, it seems that you are either a really hostile person or just having a really bad day. I hope it is the latter for your own sake.
Like others I wish you well and hope that you can find peace without having to engage in mud sliging against anonymous people on the internet.
