I don't see it happening either, no, but ones who have suggested that theory do provide evidence that corroborates it, just like any other theory. Like you said though a few posts back, it's funny to see people tell others which theory is "right" and which ones are "wrong". Unless they're part of the production team for any of these films, they don't know. I'm sure the ones who are getting the biggest laugh are the actual film makers.
Debating Rey's lineage and origin is like debating religion: Nobody knows for certain which one is "right", it's just their personal opinion and belief that's often times based on what they were told by someone else or read somewhere else.
