It's seems like you are a bit confused about DBT and how it works. It is not all about distraction. And I am unclear where you got the idea that it teaches to use deflection... quite the opposite.
As someone with BPD ... past experiences are not a good predictor of future experiences..... in fact past experiences tend to alter/skew how I see/interpret future experiences... which can lead to some messed up outcomes (to put it lightly).
I have the "Skills Training Manual for Treating Borderline Personality Disorder" by Marsha M. Linehan This is the woman who created DBT.
There are 4 modules of DBT training. When you go through the course/group it is taken one module at a time, slowly and with homework.
1st Mindfulness teaches how to bring yourself into a moment completely with all your senses
2nd Interpersonal Effectiveness. teaches how to handle interactions with people in your life.... whether it is family, friend, or the clerk at the grocery (there is a lot to this particular module)
3rd Emotional Regulation teaches how to understand what emotions are, how to reduce your emotional vulnerability and to decrease emotional suffering
4th Distress Tolerance teaches crisis strategies like awareness. accepting reality.. how to self-soothe, how to improve the moment

You are putting together different parts of the DBT training and coming to conclusions about it.
FAST is part of the 2nd module.. Interpersonal Effectiveness.... There isn't anything about standards maybe you are confusing that with the part about keeping your self-respect?
Radical acceptance is part of the 4th module Distress Tolerance. It is a tool to usewhen you are in distress, to help bring you into the moment.. not distract from the moment.
The point of "endlessly accepting negative situations and crisis" is to learn... so that when a new crisis comes, we will have tools to handle it.
If you are not BPD ... I am curious as to why your T would suggest DBT for you.
