Earlier quoted context omitted.
From what I understand, Kramnick pointed out Danya's behaviour was erratic and suspected alcohol or drug use (everyone else broached it much more sensitively, saying drugs was a ridiculous notion, and giving him space/privacy but perhaps suspecting possible mental health, mental breakdown, or maybe narcolepsy). Kramnick may have been forthright and lacking tact, but it was clear from Danya's behaviours that he sadly…
Kramnick repeatedly accused Danya of cheating, which prompted a lot of ongoing abuse from his acolytes. Danya spoke publicly about the stress this caused him several times. Of course, as ever, Kramnick had nothing to back up his claims, a fact which in no way prevented him repeating them ad-nauseum. That's not being "forthright" or "lacking tact". That's being an abusive asshole.
Kramnick's bullshit never made any damn sense at all.
