I agree that it is obvious that MAGA and too many in the right are using DEI as a catch-all slur for everybody but straight white men, and that racial animus animates a lot of MAGA supporters and is tolerated to encouraged but too many other conservative politicians and donors. It is disgusting and makes it hard to presume good faith of any conservative poster who addresses the issue.
I get where you are coming from and am bringing a personal history of good will toward 79 from a lot of years of posting on and off with him that lead me to believe he is a good faith poster, even though we often disagree quite significantly on various matters.
Obviously, it doesn’t mean I’m right — I’ve always preferred to challenge my own beliefs, especially my most firmly held beliefs, against the views of people who don’t share my beliefs. It’s what’s makes the online troll personalities so particularly frustrating to me. They just want to destroy conversations and any POV they don’t share, not debate, convince, consider or grow. They cannot tolerate the mere existence of other POVs. A lot of times the allegation of an “echo chamber” indicates a view that the mere existence of other POVs is an attack on a person’s own preferences and beliefs, as well as a complete failure to recognize that the alleged echo is people with wide-ranging opinions are united only in rejecting such intolerance. To such people, it seems that defending their world view is not a matter of discussion, debate and growth but a call to destroy all other views and opinions.
