I'm just chiming in as a queer person. There are a couple specific examples provided in the Discord, though without naming names. If you haven't been following the Discord discussion, don't have a Discord or decided not to read the links Franken provided, you probably will miss them.

I'm not speaking on Franken's behalf, but as I understand it the problem with this current rule mentioned (that being the "Respect all members" rule) is that it focuses on t[i]argeted harassment of individuals[/i], and does not explicitly cover [i]attacks on a group or identity.[/i] The change Franken suggests would make it clear that bigotry in any form isn't allowed on the site. It may seem like common sense, but I think most of you might agree sometimes common sense is a lot to ask of a person. 

In my personal experience, I have seen some jokes and comments in very poor taste on the Guild's status bar and in the Discord. Transphobic, homophobic, and misogynistic comments. To the community's credit they are few and far between. The forum itself is much better about it than the Discord in that regard as well. Anytime I have alerted a mod they have taken care of it. So you may think why change the rule if the mods handle it? It's because bigots don't see explicit condemnation of their bigotry and they think it's allowed... because the rule is about targeted harassment. And some people won't speak up or report it, because others will say that their bigotry is just their own opinion and they are entitled to it. That's why some of the people on the site belonging to marginalized groups don't feel safe or comfortable, because the Guild has such a strong stance on giving everyone a fair chance and not catering to one group or the other, that they see bigotry being hand waved. 

I don't believe the mod team is intentionally enabling bigots. I want to point out that the relatively lax moderation style of the Guild is one of the reasons I really like it. I generally think the mods do a good job too, though I haven't been a member for nearly as long as some of you. However it doesn't change the fact that some members become extremely uncomfortable and disheartened when they see bigotry being posted and ignored. A rules change that specifically points out that things like that won't be tolerated might mitigate some of it, but the most important thing is that they will feel the mod team has their back. Even if they are busy, offline, or genuinely miss something, someone can report and know that it will be taken care of because the mod team doesn't support bigotry... as stated in the rules. 

I'm lucky that I haven't encountered any nastiness in regards to my own identity here on RPG. When I see a questionable or outright hateful comment I get annoyed, ignore it and move on. I don't feel unsafe at all RPG, I like this forum. Am I still for a rule re-write to help others feel safer? Absolutely.
