Because the crimes aren’t equal. For every time a US missile accidentally hits a hospital, an Arab militant group intentionally blows up ten. For every time a US troop shoots a civilian, Arab governments kill a thousand.

“You westerners talk about your freedom of speech, but the US suppressed protests!” Well, Iran is currently Tiananmen-ing their protesters. These things aren’t equal, and it’s why the criticism isn’t equal. Don’t pretend you want equal criticism. You want the criticism of the side you oppose to increase.
