You said "we can never know". I don’t buy these way to dismiss critics, when evidence is overwhelming. Sure we can never be certain of anything. Yet we make choices in our lives, we go with what we feel is likely true. I hear a lot of such very "prudent" views about Trump and Musk. I never hear such prudent views about non-fascist persons. Suddenly the same people have strong opinions… doesn’t sound like honest discourse to me.
