I believe the answer is:

unrestricted

I'm a little stuck... Click here to teach me more about this clue!

'public' is the definition.
(similar in meaning)

'protest unusually direct' is the wordplay.
'protest' becomes 'unrest' (I am not sure about this - if you are sure you should believe this answer much more).
'unusually' indicates an anagram.
'direct' with letters rearranged gives 'ricted'.
'unrest'+'ricted'='UNRESTRICTED'

Can you help me to learn more?
