RT is beyond biased. Your claim, if true, equates all media to propaganda. Biased media is simply not the same as propaganda.
- the spreading of ideas, information, or rumor for the purpose of helping or injuring an institution, a cause, or a person
- ideas, facts, or allegations spread deliberately to further one's cause or to damage an opposing cause; also : a public action having such an effect
That certainly sounds exactly like the media's behavior in this country to me.
