My own experience with these discussions is purely what I’ve seen here in ENWorld, and mostly after I got asked to be a moderator. The discussions I saw were generally kicked off with people defending or attacking the content disclaimer on certain older D&D products.I just really have to question this. First, as someone in a very progressive part of the country, I hear about requests to simply remove content on problematic issues quite frequently. Paizo discussed removing slavery from any future APs although I believe they eventually walked it back. I am engaged in other role playing boards where issues like this come up all the time. I don't want to make the mods concerned about problematic "cross boards conflict" that's all I feel comfortable saying about it.
Most of the pro-disclaimer posts I can recall simply asked that future products be handled with care and avoid stereotyping, not asking for excisions & expungements from the games.
Your experiences clearly differed.
