To touch on the BLM bit, Elijah Shaffer on "You Are Here" gives an alternate take on how the Fox interview came about and why Kyle might have been encouraged to say these things. Starts around the 59 min mark.

Now, he could be salty about not getting first dibs on an interview, entirely possible. But given that he was on the ground and been in contact with him throughout, I think it's more probable that Kyle's PR team was swayed by Fox to do and say this.
