Bullish attitude to truth: you are allegedly excluded (3-2)
I believe the answer is:
can-do
'bullish' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for can-do that I've seen before include "Showing willingness to get the job done" , "Positive-thinking" , "Positive" .)
