Your point one is obvious and something I have never contradicted.
Your point two is misleading. The risk I state is the one in all the published impact task force reports. Your claims of higher risk are not accepted by the people most involved with detection and mitigation. When you find the integrity to admit this you may start regaining credibility with many posters here. There is nothing wrong with ignoring the rantings and estimates of net cranks when clearly contradicted by reliable sources.
As to point 3 & 4, I understand quite well how weak your estimates are. Why you choose to ignore clear data on NEO populations and lunar crater counts is beyond me. Even more murky is why you repeat errors over and over when given links to reliable sources contradicting you.
