I agree with everything you said, but I think that you may have misunderstood what Kamikaze said. (I don't blame you; it's confusingly worded) I believe what he was saying was that he criticizes trump for not calling in the National Guard, and praises Pence for calling in the National Guard. "The same" in "and praise Pence for doing the same" is referring to Pence doing the same thing that Trump should have done, but did not do: Calling in the National Guard.
I would agree that it is not the deeds of the one that exonerate the deeds of the other. Rather, it is the justification of the one's similar deeds that calls for similar justification of the other, or, on the contrary, the condemnation of the other that calls for consistent condemnation of the one. Don't get me wrong; I completely agree that the Capitol rioting was atrocious, and I think that it is a prime example of how extremists can discredit reasonable people with similar views, thus preventing positive change. I think that many of us would simply like to see at least equal condemnation for BLM/Antifa riots that were at least equally destructive, unnecessary, and uncalled for.
