As you say, we have to share a crowded airspace. The safest way to do that is to endeavor to ensure that everyone flies responsibly and, in turn, that the CAA has the confidence to set rules that let us all fly as freely as possible. The best way to do that, IMHO, is to try and bring drone pilots up to the safety standards that the BMFA holds its members too, and that's going to be a LOT easier if the BMFA stops treating the entire drone pilot community as some kind of enemy because of a small number of bad apples.
