I'll just say this and wont continue to discuss the matter.
I respect your responses here and I know those on this forum do respect each other as far as it goes. But when we are debating an issue, what we are discussing is the focus of our comments. We're looking at different points of view, which naturally is how we learn. We pick and choose what we can accept and we may then express where we disagree. Fine. But the issue is not about the author, its only about the opinion expressed, and with that we can agree or disagree. As Frank suggested we all have different perspectives on everything. Doesn't make us right or wrong, just that we are all different, genetically, through our conditionings, our experiences. We've all travelled different roads, that lead us to that perspective. We may think an argument inane, ill-informed, off the planet and that's natural but you always have to come back to the fact that that's just your perspective, your particular bias and we all have that, but its not reality, so you don't say it. We cant as they say second guess. Vivre la difference.
Now I know instinctively we all realise this, and that its the bleeding obvious, Bearfax, but its easy to start thinking we know more than the other person. However, when you start refocussing our argument to criticise the author, rather than the argument, we are in fact questioning that person's right to their opinion, judging that person, and making an assumption that we are right or know more. That's a line we should never cross in debate, because suddenly its not about the subject being discussed, its about the person expressing an opinion and their right to that opinion. 'nough said.
