The evidence is circumstantial... Steve Rogers wasn't sidelined at all in the first episode. The woke crowd dictates that you have to bury white males, which is not at all what happened with Rogers.
counterpoint: what made Rogers the ideal candidate was his unparalleled character and we've seen time and again what happens when people OTHER than Steve become super soldiers. Peggy being able to stand toe to toe with normal universe Steve does take away some of what makes him special.
Black panther being a better starlord than quill has some obvious draws to the woke narrative, but that's also not really anything new. Peter quill is a terrible starlord, but thats what makes him lovable and different. Every scene quill was in played him up as a lovable dufus. ANYONE could have had mostly better results. T'challa convincing Thanos to cool it came across as them just leaning into that to a purposefully ludicrous degree. And Chadwick boseman was awesome as t'challa so who cares.
Counterpoint: they could have gone with ANYONE as a replacement to quill but they went with t'challa because of the monolith that the woke community made him.
With episode 3, the original avengers were being targeted BEFORE the avengers were a team. The team was a bunch of white men and black widow. There was no other option than to kill off a bunch of white men in that situation. Sure they could have killed off widow earlier and made her less of a player in the episode, but I think they wanted to focus on her more just because she always ends up being a side character, so they wanted to give her more to do and a murder mystery is perfect for her to shine.
Counterpoint: the story was specifically designed to put a woman and a black man center stage against an evil white male.
