I believe the answer is:

talib

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

'fundamentalist' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'thanks liberal' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'liberal' becomes 'lib'.
'ta'+'lib'='TALIB'

Can you help me to learn more?
