Read Pariah, the new Dan Abnett book. It (possibly) has something to say obn the subject.

Personally I'd say they are loyalists, otherwise GW wouldn't have put so much work into creating the confusion on the topic. They used to be a straight up traitor legion, it's only in the last few years that the whole 'closet' loyalist thing came about.
