dcm is phenomenally stupid.
Whether he/she(?) is legitimately stupid we don't know, since we're not his parents or doctors or teachers.
However, as I might have expressed before, dcm is clearly leaning hard into his little role/reputation here as "resident dumbfuck on a niche sports team forum", so god bless him for whatever satisfaction that brings. I'm a charitable guy, so i contribute much of his "hEy GaiZ LooK at mY XtRa ChroMosOmE lolzz!!" schtick to half-assed trolling.
We should be happy he hasn't yet accidentally stumbled into a big barrel of covid while licking an oversized lollipop.
