Why do you continue to insist on asking about saws in threads that are either about potus (president of the united states!) or the current news? There are whole threads and sections of this website dedicated to saws and other equipment where those questions are much more likely to be answered, you could even use the search function if there's a particular saw you'd like to chat about.
In all likelihood most on here do or did much of their work with saws, or have an interest in trees and that's what brought them here in the first place. But much like other "industry" related forums, much of the bandwidth of the forum (too much in reality with all the bickering) is used up by people talking about other stuff.
Again, as with many other places on the internet, there are always a few loudmouths who like to show off, boast, have a debate, pick a row, play devil's advocate or just shout down anyone that they disagree with, and again there will always be those who push back against them.
With the current political situation, society is massively divided and those on either side have moved further and further apart and feelings are strong on both sides in terms of the passion they have for their viewpoint and the dislike they have for the other.
As for meeting each other and saying the same thing face to face. Some love an argument anywhere they can find one, in real life or online and have probably got into a few scrapes because of it. Many others aren't keen on conflict and physical confrontation in real life and would probably do their best to avoid the loudmouthed agressors in the first place (does that make them a coward?) which is generally quite easy as they can usually be spotted (or heard) a mile away, gobbing off about one thing or another.
