Something seems off here. Even if it was filed in Sept of 2022 (I don't see any evidence of that, apart from the top of the laWow.org website), lots of time has passed since the events alleged in the complaint - which also says all harassment claims are being pursued via the EEOC, and I'm pretty sure that process doesn't take 5+ years. And it seems that this "news" has just been made public in the last few days - all at once.
Not sure if or to the extent this is true, but I found this article -
https://coffeeordie.com/uvalde-school-shooting-solutions. The article says (among other things of interest) that the lawsuit was settled in 2019. The quotes thereafter seem a bit contrary to the complaint. Yes, the article discloses that the periodical/website is owned by BRCC.
