the logic at play for these people across all mediums is less to do with the content and more to do with the people behind it. ex. a strong female character in the past was totally cool because there was no agenda, but a modern strong female character is because there is an agenda. I am not making this up.
"Your replacing our favorite characters with SJW replacements!!"
"Like when Rhodey took over for Tony Stark before he became War Machine? Like that?"
"We just don't want the originals replaced!"
"Man you must hate Barry Allen and Hal Jordan, the second people to be Flash and Green Lantern then."
