I have a few friends who love to argue simply to argue. They know they won’t change the other person’s mind and the other person won’t change their mind. The only time I argue in a case like this is when someone makes a wild claim that I check out and find it’s unfounded or relies on flawed or faulty data. Even then, I will only push the argument so far as I find most people who choose to accept the claim are not going to change their position short of a miracle opening their eyes. However, I don’t support remaining silent when such wild claims are treated as fact when a simple search would show it’s anything but fact.
Sadly, when it comes to politics, most have no problem believing whatever nonsense their side says and don’t bother to check if it’s true. That’s true of all sides of the political spectrum. This also applies in non-political discussions where there are two or more sides to an issue.
