Here is the previous thread I referred to early, the link should point at my post where I stated what I had learned in the thread. In subsequent threads it is stated clearly that using a whistle to compliment a woman you have a relationship with can be appropriate.
You can go through the thread to see all the back and forth, and you can see my words there, but what I don’t see much more is any kind of back and forth or the attempts for people with opposing views to understand each other. That thread is a case where it worked for me. You can see this remarkable post from InternetLegend that shows discussions or that sort don’t happen often in the world, but it was the Dope was supposed to be about. There will always be people who argue vigorously but do so as part of a process to learn, and sometimes some of us go a little too far, but if we can’t back up and discuss it reasonably nothing will be achieved. Some people are jerks and will never change their mind about anything or admit they are ever wrong, and we have plenty of those here too, but there is no point focusing on those attitudes because then reasonable discussion and the possibility of mutual understanding disappear.
