Kapitan, I agree with you. I have asked and asked around on various forums, but I haven't found any clear explanations. The toxic Critical Race Theory appears to blame everything on white males. That is, facts don't matter when neo-Marxist ideology wants to impose itself on society. Has Microsoft adopted such a racist neo-Marxist policies? Their actions speak seem to confirm that.
Racism, age bias, and sexism (on the part of Microsoft's decisions) aside, I would be happy with add-on avatars, including some goofy-looking science fiction characters. Also, I wouldn't mind have my Labrador Retriever as an avatar as a passenger or co-pilot seat.
