Why did the anti-imperialist league argue against the u. s. occupation of the philippines?

Ahhh I remember this from 8th grade! Alright the Philippines was already trying to break free from another occupied force in the Philippines and so when they teamed up w America, the Americans say they will but never explained that when they do help they will take over, so when the American force helped the force that was trying to get rid of the occupied force, the Americans occupied it. The Anti imperialist argued that its their land and rightfully so but u see America was on a race with England to gain more land, but still America gain control of Philippines, while the anti imperialists fought, the American soldiers not only fought but raped women as well.
