Thanks Dennis!
I think my response is me trying to indicate that I see his point of view, but also want to further elaborate on my point of view. I wanted my response to be gentle, and that might be why you get an "apologetic" tone. The last time I wrote about this topic, it was more of a rambling rant, less composed and justified as it is here, and a Russian white woman commented some absolute BS and I completely insulted her in my response. That was about a year and a half ago, and since then I decided I want to avoid doing that.
Also, when they hit me with the class argument, although I know it's incomparable, it tugs on my heart strings a bit that there really are a ton of poor whites who are very likely also racist. I wish that poor/middle class/rich whites would wisen up about racism and actually care. So what you're hearing is frustrated kindness. I'm frustrated that no matter how well we say it they refuse to get it.
Fortunately I believe that God will deliver us from this mess one day. Cause these white people are set in their ways - irredeemable.
