I think we all know that there is a real issue with lack of diversity in the RPG world in general. I think we also all know that WotC has done a pretty good job in making their company diverse with key jobs, so I agree with you, and the comment like his/hers above is unwarranted. I think it's a bit of a conundrum. Our hobby is overwhelmingly white male. Better in recent years, but historically very much white male dominant. So if you open a job opening that requires years of experience and accomplishment in this hobby, the candidates are going to be overwhelmingly white male. That doesn't mean there aren't non-white male candidates out there, but they are going to make up a very tiny % of applicants (and WoTC has hired non cis white male people in key areas). Because of this, if a company focuses on hiring non white male primarily, then other more qualified candidates may be passed over. It's a crappy situation all around. We want more diversity in key jobs, but should that be at the expense of more qualified people? I'm not going to say either way because I see both sides of that.
What I will say though, is that it's a clear reason why we need to support and encourage more diversity for those in the entry level jobs and indie companies. I.e., we need to give minorities that experience so when higher level key roles do open up, we have a much greater diverse and experienced applicant pool. Address the root issue, IMO.
Either way, I wish we could be at a point where when someone gets hired for a job, we can assess it by qualifications and race/gender never comes up. I wish people would stop making comments that the only reason person A got hired was because they were a minority, or that if they were a white man, it's the company being unfair to everyone else.
