You're quoting a unique cell with human DNA as a person. A human being. Where most on the left would recognize that as potential to become a human being. As they recognize a human being as more than a cell with human DNA.
It would be the same distinction one would draw if one were to recognize that an acorn is not an oak tree. Where by your logic, an acorn is an oak tree.
I feel like you're trying to write the issue of abortion specifically between the lines. Read only what I actually said and you'll be closer to what I was actually saying. That's explained again below in my reply to Sonny Clark.
Could you break that down for me, please? What are you talking about? What about biology? Who doesn't want to listen?
It's not so much that anyone "doesn't want to listen". It's that we're seeing reality from two almost completely separate viewpoints. There isn't really any common ground between the idea that the reality I see is objective and exists regardless of whether I'm looking at it or not and the idea that the reality you see is subjective and exists only insofar as everyone agrees that it does. Normally the two can still coexist somewhat peacefully, but, well, to be totally frank it's shit for discussing science.
Well, we have almost seven billion people on this planet, and at least that many views and opinions. And, each is entitled to their own thinking and reasoning. You're not going to find 100% agreement, and if you ever do, it'll be very rare, very. There will always be those that see things from a different angle, and they sometimes reason their view 180 degrees from everyone else.
It never hurts to discuss issues, and most of the time, everyone learns something new from those discussions. We will always disagree on matters such as religion, politics, creation, evolution, global warming and climate change, wars, the death penalty, abortion, the right to keep and bear arms, taxes, campaign financing, subsidies, foreign aid, foreign trade, illegal immigration, and many other topics.
Don't get upset with folks for disagreeing, get upset when folks refuse to discuss important issues. If we never discuss problems and possible solutions, nothing will ever change, and nothing will get done to rectify wrongs. We discuss issues hoping that those conversations will find their way to the right set of ears, that have the means and power to act and bring attention to our social and economic woes. Planting seeds of thought is all it takes to bring about much needed solutions to today's problems. Every act starts with a seed of thought. Never give up trying to make a difference.
