I absolutely agree with you. Never have I felt in this comic that the anger is unjustified. It is very clearly stated Why the character is angry, How they got angry, and it doesn’t invalidate the anger they Express too.

I think that the reason the anger works, is because you can understand where the anger is coming from. You might not like the character, or agree with what they are angry with, but you understand why that character is angry and why that was their breaking point.

Hussie did a good job in showing their anger for every character, and not excusing it or belittling the reasoning for it.
