I understand Radical Acceptance but when it comes to this type of issue, really??? I don't know. I can accept some things better that others, core believe issues are a different story. I can accept that half or more of what's presented on the news is slanted one way or another, depending on the news station, that still does not change my feelings about the subject matter.
I didn't find the radical acceptance section in Chapter 1 helpful. I didn't get it until I looked ahead in the book to where it's explained later in more detail, and in the context of dealing with everyday life issues.
Those exercises, especially the news story one, just confused and demotivated me. I'd recommend skipping them. I thought it was more useful to read the later explanation and try to think about applying it to smaller things in everyday life.
When something goes wrong I tend to think that's typical of the bad hand I've been dealt, even a small thing can't go right for me, etc, but using radical acceptance I can see that it's not personal and I might even be contributing to it (to be honest, I think my part in it is the most radical thing for me to accept, lol). That's not to be hard on myself about that, just to identify what I have the opportunity to change in future, or what I have to accept and let go of.
