No it isn't. It's defensive and reactionary and stifles progress by taking people of color's social criticisms as personal attacks. We should recognize modern systems of privilege and discrimination. It's not about blame or making people feel bad, those are internalizations the dominant group has (in the case of race, white people) and aren't often productive. Most of us don't want to admit we've benefited from exploitation or started with a head start, especially when our experiences don't include the absolute hell of modern racism. Unless we're part of a social minority group we aren't exposed to the crap they go through. All of this stuff has historical context too, it didn't just happen out of no where, which is why history is brought up. These problems are ongoing, not buried in the distant past, and must be acknowledged by the dominant group. Please do your part to end the vicious cycle and listen with an open mind to the voices of people who are part of a social minority. It's minimum human decency. It's not always easy, believe me, as a member of the dominant racial group I know, but realize that as difficult as it is for you it's a trillion times harder for that person who's opening up to you, expressing their hurt and frustration at inequality that has benefited you and screwed them over. At the end of the day you can go home and blank it out to revisit later but they can't. It's pervasive, stalks them, infects everything, and can't be cut out of their lives. So keep that in mind if someone ever offers you their perspective as someone from a minority group
