I had to cut for brevity, but number 6 stood out to me. Tamar's apology IS an apology when she's said for months I DO NOT KNOW WHY MY SISTERS ARE MAD AT ME. Toni tried her damndest last season to make Tamar apologize to the other sisters without hearing her when she said she doesn't know what she did. At what point does the onus switch to Traci, Trina, and Towanda to be a goddamn adult and say, "I am mad at you because {insert reasoning here}"?
When she is confronted directly in one on one fashion she can and has given a real apology. But you can't be fake mad and shocked you get an incomplete apology.
