It's worth noting, though, that the most of people's disagreements with Blue came from the politics and religion threads. He could of easily stayed and contributed to the site while staying out of those if he couldn't handle it or didn't want to handle it or whatever the situation is.
It seems to me Blue was ready to be done with NSM, unlike Deku who seemed to just gone on indefinite break rather than saying "I'm gone and not coming back" kind of thing.
