Why is blatant historical revisionism so widespread today?

Some modern examples

1. Europeans started the slave trade (... omg)

2. Native Americans were peaceful (what?)

3. The US lost every war since WW2 (😂 wtf?)

4. Palestine is the historical territory (🤦‍♂️)

5. Democrats have always supported minorities (🤮)

6. The Islamic Conquests never happened. (...)

7. The Crusades were purely unprovoked. (.. help us)

And many many more nonsensical claims. People are generally very historically illiterate.

It is normal for events to be differently. For example, the Settler vs Native conflict used to be perceived as a clash of cultures before the 1960s, now its largely viewed as Imperialism. Both are correct. That is often a reality of how different eras of people view the past. Sometimes, positive outcome are short-lived and after lasting negative impacts. Obviously, figures will see the event differentlym

However, the need to completely rewrite history seems common today. That is different.
