Consumer hassled Netflix about opera content (11)

I believe the answer is:

flexitarian

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

'consumer hassled netflix' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'about opera content' is the wordplay.
I cannot really see how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is located in the answer.
'content' could be 'an' (AN is an example) and 'an' is found within the answer.
This explanation may well be incorrect...

Can you help me to learn more?
