"God is not pleased."
Well, according to your faith, that's true. Hinduism has other beliefs, and building such large statues is part of those beliefs. They believe that their deities are pleased by such, so they honor them by erecting these statues.
And there it is.
Ya and for most of recorded history, people "believed" the world was flat. It was never flat. God "is" and no other beliefs are going to alter that.
