Hello, I have not read the full thread, and I apologise for the derail from the Karen discussions, but the OP mentioned at the start trying to learn more about race and racism since the BLM movement kicked off.
May I ask if the OP has read or watched any material that is not supportive of Critical Race Theory? A lot of the current mainstream discourse around racism pushes a very specific ideological narrative. People from ethnic minorities are very varied in their opinions and ideas, just like anyone else, and there are those who disagree with the popular and more trendy narratives. A number of them are increasingly concerned by the underlying assumptions and directions being taken by movements such as BLM and the implications this has on common shared values in our society based on enlightenment principles.
A lot of people on the left or liberal side like to talk about 'uplifting' or 'centering' the voices of black people and other minorities. However, this only applies to those minorities who toe a very specific ideological line. Those who don't are at best ignored or at worst targeted in various ways or even called some awful names.
In the interest of learning about racism, I've found it helpful to read the views of those people of colour who are often ignored by current trends, even if I might not agree with all of their political leanings. I'll list a few below.
The Equiano Project has been recently started by Inaya Folarin Iman. She explains why she did so.
Not specifically related to the above discussions, but a more broader look at the topic.
I also like to read quotes by Thomas Sowell on Twitter.
There is a lot more out there, but hopefully the above gives you, and anyone lurking, a starting point for more nuanced discussions.
