No, that would be so unfair...whether you like it or not, Gerberts exist and some of them are amazing. If you don't like them, think about the people who are looking to read one and they have to surf through all the other crap in this section to find even one. It's even more difficult that finding a Frerard.
If there was a subcategory among the MCR section, it should just separate slash from the normal girl-fucking-the-band fan fiction, and then maybe there could be further divisions. Because as much as I enjoy Frerard, it doesn't deserve some sort of special VIP treatment. There are plenty of other pairings.
