And, actually, I did know that about you because you've brought it up before. Your daughter's choice of a husband does not inoculate you from being racist AF.
The last time it came up I asked you to go have a conversation with your daughter to ask her "hey, honey, have you ever said something like this to the grandbaby's 'sweety, grandma loves you very much, but sometimes she's gonna say things about people that look like you and daddy that are going to sound really mean, but you just gotta rmember that she loves you."
Did you ask her? I bet you didn't. Because the answer would be "....(very long pause).... no, mom. (very long pause)"
And you know those long pauses would really mean, "yes. I have."
And you didn't answer my question, have you ever said something like, "My son-in-law is great, his hispanic but one of the good ones. You know what I mean."
Because you have to mention that he's half white. Because when you say things like that, it means "half of him is bad, but the other half is good. The white half."
There's no need to qualify his heritage beyond your racism.
