Broad-minded (7)
I believe the answer is:
liberal
'broad-minded' is the definition.
(similar in meaning)
This is all the clue.
(Other definitions for liberal that I've seen before include "magnanimous" , "Favouring individual freedoms" , "Permissive about Braille" , "Generous; broad-minded" , "Favouring a political philosophy of progress and reform" .)
