I'm assuming you're referring to BernieBros and "brocialists", in which case at least we're working on that. If there's an "alt left" it's far more diverse than the alt right is and we have constant fights between those who believe in intersectionality and those who still cling to class before anything else, while the alt right by definition is entirely regressive and reactionary.
I'm pretty sure we're talking about white liberals who don't happen to be very liberal when it comes to race, and not about singling you out. Young whites not being very different to old whites on races, compared to young blacks.
Yet many millennials subscribe to this view, with an MTV/ David Binder poll finding only 39 percent of white millennials believe white people have more opportunities today than racial minority groups. By contrast, 65 percent of people of color feel that whites have differential access to jobs and other opportunities. Further, 70 percent of all millennials say its never fair to give preferential treatment to one race over another, regardless of historical inequalities.
In a 2009 study using American National Election Studiesa survey of Americans before and after each presidential electionVincent Hutchings finds, younger cohorts of Whites are no more racially liberal in 2008 than they were in 1988. My own analysis of the most recent data reveals a similar pattern: Gaps between young whites and old whites on support for programs that aim to further racial equality are very small compared to the gaps between young whites and young blacks.
And even though the gaps within the millennial generation are wide, as with the Pew data, there is also evidence that young blacks are more racially conservative than their parents, as they are less likely to support government aid to blacks.
Spencer Piston, professor at the Campbell Institute at Syracuse University, used ANES data and found a similar pattern on issues relating to economic inequality. He examined a tax on millionaires, affirmative action, a limit to campaign contributions and a battery of questions that measure egalitarianism. He says, the racial divide (in particular the black/white divide) dwarfs other divides in policy opinion. Age differences in public opinion are small in comparison to racial differences. This finding is, he adds, consistent with a long-standing finding in political science. Piston finds that young whites have the same level of racial stereotypes as their parents.
That discrimination affects whites as much as other minorities...
A 2012 Public Religion Research Institute poll found that
58 percent of white millennials say discrimination affects whites as much as it affects people of color. Only 39 percent of Hispanic millennials and 24 percent of African-American millennials agree.
The kind of liberals who argue protests should be quiet and not clashing with an opposite group. The kind who concern troll that BLM activists shouldn't interrupt events, that they should be calm and respectable even when black people are still discriminated/murdered/incarcerated at disproportionate levels.
