"Marginalized" groups have not been helped in any way by any of this. Lumping everyone together into a group who is not a white straight man diminishes everyone's individual
material problems into a generic "marginalization," and unfairly
centralizes white straight men. It's something that wealthy powerful people do in order not to have to discuss their wealth and power, and the fact that they all grew up in sundown towns.
This wave of wealthy white people screaming "bigot" at other white people without health care hasn't raised the condition of the descendants of slaves at all. Instead it's been an expansion of welfare for well-off white women and affluent immigrants. Everybody has been oppressed like black people except for the descendants of slaves, and everybody has been stuck in a caste system except for Dalits.
"Marginalized" people want to be addressed as individual humans with material problems like other humans. Instead a bunch of people so wealthy and comfortable that they are almost completely detached from the material world and have never missed a meal treat everyone like symbols and try to read the world like literary critics.

Assuming that everyone you're talking to is "the many" is not good. Your argument should work no matter who you happen to be talking to.
