If you erase/destroy all alternative experiences and ideas to what is not conguent to the official accepted narrative, you have a population of people who are willing to believe everything those in power show or tell them. It's in the Marxist hand book with Marx, Mao Tse Tung (and some would also argue Antifa) using this technique to bolster their followers.
Yes, I believe this is what is happening. I also see the SAFE SPACE movement as a new tool in this arsenal.
If you want to go back even further in time, you can go back as far as the Egyptians who destroyed the name and likeness of anyone that they disagreed with from the statues and monuments.
I'm pretty sure I made reference to that in my post.
So are you saying you advocate such behavior? I am unclear from your response.
Like you, the editing of history bothers me a great deal. I'm known to keep the original hard copies of books just in case they are altered and have rescued many tomes from the trash.
