Aw hell naw. There might be some idiots who will go there, but I guess you're specifically referring to Bernie's supporters, and you couldn't be more wrong.
The idea was never to throw out Muslims, immigrants, and LGBTQ people to the wolves. Give us some fucking credit dude, Bernie himself has defended these causes for longer than the DNC as a whole. The idea was that we should focus more on economic populism because it *works* and would help us win the elections we badly need to win.
What's the alternative? We ignore populism but focus only on identity politics, keep losing every single election we could lose in the US (as has happened since 2010, with the sole exception of Obama), then all of those minority groups are completely fucked because we're powerless while Republicans control the entire country.
