The only video I'll miss from Somerton's channel is the video on "LGBTQIA+ alphabet soup vs reclaiming Queer" (whatever its actual title), because I think it is a genuinely important contribution to queer discourse which too often refuses to say "queer" as not to offend a small subsection of older queer Americans...
But the alternative is an incomprehensible jumble of letters which necessarily in its attempt to explicitly include everyone always excludes someone (and anyway "LGBTQIA+" may or may not include all of "agender, asexual, aromantic" so how is that any more descriptive than "queer"?).
At least "GSRM" is not inherently exclusionary, but unlike "LGBT" or "queer" it's not widely known and doesn't roll off the tongue so I still much prefer "queer" outside of academic discourse where "GSRM" belongs IMO.
