Make no mistake about it. Propaganda and mind conditioning techniques are alive and kicking. It's easier now compared to how it was done during the yesteryears with the technology at the disposal of those who intend to do it. When you think you are good enough not to be affected by it, then you make yourself more vulnerable. Once you find yourself hateful of a person or a group and sounds like you're ready to bite at anything that is about them no matter how harmless the news may sound, then you are infected. You will not accept any reasoning at all. You are not willing to meet in between nor even agree to disagree. You just want them destroyed. You want them to disappear. You are hateful. You are mind-controlled.
What you can do to get out of it is to realize your own humanity. Your frailties as a person, that what you are is not far from what others might be. That there are considerations that they have that we don't know about. That there are factors that are affecting these people that we are not aware of. After doing that, you still might not agree with them strongly. You might still have the same stand. But you'll lose the hatred. You'll snap out of the conditioning. And you'll start to stand (again) for your principles.
