"On the other hand, published data which proves that (say)violent crime is highly correlated with abortion laws in the US (i.e. when laws are changed to allow choice, crime statistics begin to improve 15-18 years later in almost every case and stay that way; when laws are changed to make abortion illegal, crime statistics suddenly get much worse 15-18 years later, and stay that way), seems to be completely ignored by the anti-abortion lobby."
That statement certain gives me enough information to derive your viewpoint. I also question those findings, what is it based on? abortion has been legal for quite a while.
"Why not respond to the actual points I am making?"
I did, I said you were making quite a spin out of the facts. You implied they might be falsifying data because the other side was perceived to be unfair in criticizing them so in order to win the issue it was justified. Because they are right of course. That is the end justifying the means and I rightfully point out that this type of thinking is what ends up causing the vast majority of conflict in the world.
"1. A person's starting perspective automatically biasses the lens they use when looking at a situation or set of data."
Sure, I agree.
"2. There are no absolutes in this kind of complex issues. You and I are not omniscient, and do not have the right to judge another person's motivation for doing something."
I can make any judgment I want, we still live in a somewhat free country, at least for now. People's motivations are really important points to consider in an argument.
You yourself point out multiple times that we approach the issue from our own particular lenses, it is pertinent.
"3. There are a variety of ways any information can be interpreted. Our starting perspective and the relative important of evidence and belief in our thinking processes are critical to how we interpret the data."
OK I agree somewhat
"4. In the end, it doesn't really matter if the environmental crisis on earth is entirely man-made, partially man-made, or not man-made at all… what matters is what we do about it starting today."
It makes all the difference in the world since the remedies being proposed will have substantial economic impact on society. If it is not man made then taking drastic action is not a very good idea, and it would be futile. In fact the evidence apparently shows global cooling might be occurring.
"Anyway, please let's keep this civil and not attack one another. Most importantly, please don't ever make another judgement about MY motivations. It is rude and goes against God's commandments (Deut 5:20) as well as the rules of civil society."
Pointing out your possible motivations is not an attack, it is key to the discussion, the consideration of peoples motives is very important. And pointing out that I am disturbed by certain comments in not an attack either, I am opposed to the ideas and comments not to the people making them. I have nothing personal against you and would be happy to sit down, chat and have a beer with you. If you perceive any personal hostility I assure you there is none from me.
My comment to DaveT was a wisecrack in response to a wisecrack, hopefully taken in good fun.
