Im curious what do people think of the Twilight series? That is far more abusive! I remember loving it as a teen but there were times i thought why is she putting up with that?!
Then reading/watching the films as an adult i was shocked how bad it was.
Granted i havent read HP since maybe my early 20's (only early 30's now) but i never thought it was abusive, i thought Ron was a bit a twat at times to everyone but i thought it was because be was so insecure.
I have read so many books where the relationships are damaging/abusive i would never have put HP in the same category. Heathcliff/Cathy? Thats an awful relationship!
Though i guess i can see where some people are coming from that they see an abusive relationship at home and then read it in their books that it might cement the thought that its normal.
