Okay, I understand your reference better, now. Those are factual accounts that their schools had failed to teach them; so they're hearing about it for the first time, and, presumably, you've already established a rapport with them prior to that?
I guess their P.O.V. is so foreign to me *BECAUSE* I've read so much about systemic injustices -- and I have to remind myself that not everyone has the same breadth of knowledge that I do. So then, when I learn about new historical facts, I already have an established inventory of knowledge to draw uipon and to which I can add the new things I've learned.
But would they really be inclined to view the info with SKEPTICISM if they were hearing it from someone who was Black, Indigenous, or a Person of Color -- rather than hearing it from you? That's what I was getting at. Or, it is mainly BECAUSE OF their preexisting affection/connection with you (in terms of familiarity and interaction) that they become willing to digest those facts?
As far as my interactions with other ruralites and with Republicans -- well, I live with two hard-core Trump supporters (my parents). I have to cover my ears or talk really loudly whenever I pass through the living room (if I'm not the one who'd been watching the TV), since Fox News is usually playing at a very loud decibal.
The answer is: you learn to work around it. Often times, I find myself initiating topics of conversation where I know I already agree with my parents or my sister about something specific. Or, when interacting with conservative-minded people outside of my family: I just spin the discussion to a point that I hold dear...and I can usually end up creating a scenario where they agree with me on something, even if I'm not changing their minds entirely.
