“I would also highly recommend sending this article to any liberal friends who subscribe to Rolling Stone”.
I agree but from experience trying to rationalize with Liberals/ Progressives, it would not sway many, if any, of them a bit.
There is one old guy holdout Liberal among the group of older guys I socialize with. He drops into our spot when he's in town, every other month or so. For years people (he likes) have gently been telling him: "You aren't a liberal and you shouldn't be a Democrat anymore".
This last week he said, while he thought Trump went to far in his rhetoric, he was going to vote for him because Lizzie Warren is a Socialist and he could never vote for someone that far left.
There are still a lot of people who don't understand what the modern Democratic party really is all about, and we have to find better ways to get the message to them. I think that seeing a hard-hitting condemnation of the Leftist media - by a highly regarded Leftist media star himself is about as good as it gets.
But ultimately, you are right, it's very hard to convince most leftists of anything.
