CMV: Many racist believe they aren't racist because for decades society has taught that racism is bad. But they believe themselves to be a good person. Therefore what they believe must not be racist.

I believe this can be applied to a wide range of other isms but let's stick to racism. 

I hold this view because I believe more people than the plain old blatant racists that exist in the world that everyone can identify are actually racist and this is my explanation as to why it isn't acknowledged more broadly as an issue, particularly by racists. There are also different level of racism in the world so I am not saying that there is a large portion of the population that would lynch someone. However, if a person sees some of their beliefs in someone they will be more lenient in finding an alternate explanation.

So racism, loosely defined, is the discrimination against a person or group based on race. For decades society has taught that this is wrong. That harboring racism is bad. However, I believe there is a large swath of people in society today that still hold racist beliefs but believe they are a good person. They have proof that they are good because of a number of other societal metrics that they meet they are a good person. They might follow the law, possibly a good Christian, volunteer for charities, or any number of highly valued actions in society or maybe just don't do anything they deem bad. So if they are not bad they must not be racist! And if they are not racist then others holding similar views must not be racist either! 

What comes after that varies from ism to ism but for racism I believe it turns into something like "I am good person so I am actually defending myself, and other that believe this, from outside threats. We are the victims!". The Civil War becomes defense of states rights. Opposition to the Civil Rights movement is rolling back government over reach. Voting rights restrictions are securing our elections from threats. But certainly not racist.

Edit 1: I did not call you, your mom, or everyone racist. Just my belief that racists exist that deny their racism. I did not say any political view or shade of skin was immune from being racist. I do not hold those beliefs nor are they present in my view here. 

I do not believe that all racism is equally bad or that even a small amount of racism automatically makes you a horrible person. I believe it's a spectrum of bad that people will jump through a lot of hoops to not be labeled with to maintain their "goodness".

So you’re asserting that “many racists believe they aren’t racist,” due to lack of self awareness and confidence that “they believe themselves to be [good people]”. 

How could one change a generalized viewpoint like this? (It’s also conjecture; we can’t point to data to change your mind.) Are you looking for anecdotes?
