Liberals use the Boogeyman of the ignorable "Russian troll" to protect themselves of criticism of the Democratic Party the same way the Republican Party uses "Youth Snowflake".
It's an easy out to pretend that anyone "reasonable" wouldn't say anything that makes you think the party isn't doing enough and hurts your sensibilities of good.
Once again the moderate upper middle class asking that nothing change until they are done being happy because it makes it easier to ignore the cries of those suffering.
Neat.
