I understand that but in "the West" you had political pluralism which meant you could have *at the same time* both people condemning human rights abuse in communist Poland and useful idiots marching against NATO and for unilateral disarmament.
In case of Eastern Bloc it was all simple - if there was decision from Moscow we now support Palestine Liberation Organisation, we all marched in support of PLO. When Moscow decided we no longer like PLO, we marched against.
