While the complete truth, without any subjectivity, is sometimes difficult to say it, some people intentionally mix truth with lies (possible truths that are lies), and this is often called disinformation. People that are into disinformation are sometimes called conspiracy theorists, trying to uncover deep/hidden truths. Some people spread disinformation for fun (trolling), but others are following a precise agenda (often political propaganda); and even, sometimes, religious people spread ideas following that devious path.
