1st, it certifies the present conditions as inevitable and immutable. As the way it needs to be. As what's "real"
2nd, it drains energy from people of resolve and imagination. There's little more demoralizing than one who only agrees with you in principle.
(*not to say we were in a good/great/perfect place before, but this is a worse place)
It's an advantage we give up, by insisting on being "realistic."
Every "realist" I talk to seems to believe it, tho.
They received SO MANY reflexive answers along the lines of "that can't happen."
I just didn't have the energy for it.
We'd all better do the same.
Or, if you can't, then at least shut up. You're draining 'unrealistic' people of imagination who are doing crucial work.
Just being realistic.
