"Just as black trans women are important to us in real life." That sounds...so patronizing...
Does Lou really think that this is the first trannie character to be shoehorned into a comic, or does he only care about it because Wonder Woman? There were some in X-Men: New Mutants. Barbara Gordon had a trannie roommate in Gail Simone's Batgirl. Lots of comics have been incorporating dumb woke bullshit, for a while now (at the cost of their core readership).
A more apt representation of Lou would be the super-failed, canceled before it even got released Marvel New Warriors team, including such characters as Snowflake, Safespace, Be Negative, and Screentime. It was so bad and over-the-top that it was hard to tell if it was even real or a parody. That represents Louie Boy way more than a black troon ever would.
