If it wasn't for the constant propaganda that Americans are exposed to far fewer people would think that the founding fathers symbolize that. People believing in lies doesn't make the crimes of the founding fathers acceptable. And believing those lies causes people to blind themselves to the reality of America and its crimes. When people believe something other than the truth it leads them into a future that doesn't learn from the past.
Look at how much the situation in Palestine is changing the opinions of America. Many people are seeing the full extent of America's violent foreign policy. It's shaking their belief in America as something noble and freedom loving. I believe this is a good thing. More people's political opinions will be rooted in the truth. It could effect how people vote, protest, organize. I think this could lead to positive change.
Are you saying that people shouldn't care about the truth? What is your point exactly? You haven't actually stated any belief. Is it important to you that America is seen as noble, independent, freedom-loving, bold and courageous? Why is it important to you that the founding fathers are seen this way? Why do you think its ok for people to believe lies when they've never been offered the truth? Why do you value the mythology of the founding fathers more than the reality of the founding fathers? You called me childish for caring about the truth of the founding fathers, and for not valuing the lies about the founding fathers. This is insane to me.
The founding fathers were both of these, and what they represent to different people depends on perspective and world view.
Some people's perspective and worldview are wrong. It seems like you think tribalism is when someone thinks their worldview is right and someone else's is wrong. What is your political ideology? That seems like a centrist take if I've ever seen one.
