How is it hypocritical? Either the sources are biased or not. The poster not providing proof for a counterargument is irrelevant. Or do you mean they should provide proof for the original sources being biased?

It is hard to agree to a statement like “USA doesn’t like when their people are attacked or killed” when you consider that they are currently starving their poorest because they are having a budget fight over wether to take away health care for a good chunk of their people or not.
