I'm Russian, and this is nonsense. The Civil War that followed is definitely recognized as very destructive and traumatic. But it doesn't mean that we don't remember the Attack of the Dead Men, the Brusilov Offensive, the Women's Death Batallions, the Brest Peace etc.
When it comes to politics, in particular, WW1 is remembered precisely because it led to a revolution, and it was very obvious and explicit in the revolutionaries' rhetoric; one of the most famous slogans was "штыки в землю", literally "bayonets into the ground".
Thanks. I'm not Russian, and if someone says WW1 is largely forgotten there, I'm doubtful, but I'm hardly in a position to argue.
It's mostly forgotten in the US, for that matter. I think the last living veteran of that war died recently. Peter Jackson's recent cleaning up of the movie footage for "They Shall Not Grow Old" https://www.imdb.com/title/tt7905466/?ref_=nv_sr_srsg_1 was heart-rending.
