Does a racist know they are a racist?

Race doesn't exist, racism does. But we can now confine it to opinions and not pretend that there might be any scientific validity in bigotry.

Only for the hard of thinking.

Racist: (noun) a person who shows or feels discrimination or prejudice against people of other races, or who believes that a particular race is superior to another.

"I'm not racist because race has been scientifically proven not to exist. Did you see all those dark skinned people on the news, we're being invaded, it's an outrage"

Edit. Can you imagine what the judge (enemy of the people ) would say to someone using that defence in a court of law if they were up for inviting racial hatred.

Are people who prefer to live among people with the same language, ethnicity, religion, and general culture, education and outlook, racist?

It's hard to discuss the topic when you are met with such zealotry.
Racism exists because the law says it does. It is a tool for law and it is a convenience for the self interested and the virtue signaling liberal.
I'd suspect that a mistrust of people who are different or newcomers is born partly from nature and nurture.
It is almost certainly a defensive mechanism on one level and sometimes born out of personal experience perhaps or a perception based on observation. In some cases it might be misplaced, but it is very human.

Those who are obsessed with exposing it obviously have some desperate need to feel worthy or righteous for reasons that must say something about their own psychological issues or personal history. It is particularly odd when they invent and misrepresent in order to achieve this.

What, for the reasons I listed, or for other reasons?
