I agree with @SenorBeef. I haven’t been a poster for 20 years, but I did lurk on and off for at least a decade before I joined, and the open and wide-ranging discussion was one of the things that drew me.
By all means require content warnings and serious treatment of serious topics, and disallow contentious issues in the more chatty forums, but don’t ban discussing them altogether. I mentioned that I found an earlier hypothetical from @Max_S disturbing enough that I muted it, and I still don’t want to see difficult topics made off limits in GD.
(And what’s up with the posters saying ‘white male’? What on earth does race have to do with the issue?)
