All of my attempts to write Serious, Emotional fiction result in a second person POV. How can I get the world at large to appreciate second person so I can get on with being a Serious, Emotional writer who doesn’t spend hours editing out all the “you”s?

This is surprisingly simple; identify people who dislike being told how or what they feel, and kill them.  Eventually everyone left will like second-person writing.

In the unlikely event that this advice won’t serve, you may need to think about why it is that people dislike second-person writing, which is that it is typically uncomfortable and creates a barrier to willing suspension of disbelief.  If you are unready to kill all the people for whom this is uncomfortable, you may have to accommodate them.

Typically, one reason to pick second person is because it creates immediacy (this is your problem; immediacy can be very unwelcome, especially if people find the character hard to relate with).  The second is that it provides a context where it makes sense to disclose someone’s emotions; here, however, it’s counterproductive.  See.  Telling people how someone feels is never going to carry the impact of showing how they feel.  Even with the immediacy.  So if anything, you should probably move as much as possible to third-person non-omniscient, so you can’t talk about how people feel, only about what they do.  And use that to show emotion.  Because while this is harder, it is also a way to give the emotions a stronger impact.
