Iron golems does not attack the player when player hit the golem in hard difficulty

they don't attack you if you made them with 4 iron blocks and a carved pumpkin

It is true Charlie Hilvert has the reason, i don´t know iron golems does not attack if you made the iron golem, but other iron golem attacks, one more thing now i know about minecraft, incredible, i am old gamer (4 years) and i know this now, so sorry about open issue.
