In this case (as I said), it is irrelevant. To point it out is to cast doubt on the truth of what she is saying, because socialists lie - right? But in this case, she's telling the truth about the horror of the holodomor mass murder. So casting doubt about that is not helpful.
I had no intention of casting doubt about Holodomor. It was in fact genocide by Russia under Stalin.
BUT, I feel it is appropriate to caution about a writer with admitted Leftist perspective when it is posted on FR.
I even questioned the writer directly about her perspective. Did so on Twitter. Have yet to receive a reply.
