I'm trying to figure out why you said both these things that seem to directly contradict each other. The former statement is obviously bogus (for one thing, it overlooks that Captain Marvel did quite well), and the latter statement appears to be debunking the former (as well it should).
The first sentence used the words "seems" and was a response of a previous list which stated that nobody wanted to see certain movies--and nearly all of those movies had non-white and/or non-male leads. The second post was a response to a follow up post where I stated my opinion that I don't really agree that that is the reason those films weren't as well received or as successful. Captain Marvel, Shang-Chi, and Black Panther were all really well received movies, for example.
