Harry Potter a blatant Ender's Game ripoff. (Score 1)

This is kind of off-topic, but does anybody else think Harry potter is a blatant Ender's Game ripoff.

Hogwarts - Battle School
Quidich - Battle Room
The schools separated by teams in competition
Teachers play same role
Brilliant/Magical kid taken away from his family to fulfill his potential at Battle/Wizard school
Harry's friends and Ender's friends have some parallels

(Please excuse my spelling on the Harry Potter items)
