Liberal, easy, not into enforcing norms toward beginners (7)
I believe the answer is:
lenient
'liberal' is the definition.
(thesaurus)
'easy not into enforcing norms toward beginners' is the wordplay.
'easy' becomes 'le' (I am not sure about this - if you are sure you should believe this answer much more).
'beginners' suggests taking the first letters.
The initial letters of 'not into enforcing norms toward' is 'nient'.
'le'+'nient'='LENIENT'
(Other definitions for lenient that I've seen before include "Mild and tolerant" , "Forgiving, gentle" , "Forgiving, soft" , "Soft-hearted" , "Indulgent, lax" .)
