You see “Us Versus Them” mentality play out all the time. And it’s always the other side that’s evil. That is not helpful at all and that untruth is the cause of our conflicts to begin with. Human stupidity is underrated. People usually don’t take into account that we are irrational by design, that we make make mistakes and miss the details all the time. For some, it doesn’t even occur to them that they are missing something.
The point is you are never free from thinking irrational. Even the things you know as “facts” may be wrong, incomplete or obsolete now. So you are just as likely to fall into traps from various sources as the “others”. Some awareness, man. You walking around blaming people isn’t fixing anything. Maybe the mistakes they are doing are exactly the same as yours or something of that sort. Have some compassion for others.
