Nobody's being intolerant of Stealth Symphony fans; there'll always be fans of even the worst-performing series, not that we know for sure if Stealth Symphony will be one. We're just pointing out the potential, objective flaws we think the series may have that will threaten its survival.
Also, you can't deny Viz's extremely poor choice of series.
In ESJ's almost two-year run now, the only series Viz managed to pick to be simultaneously released in Japan and the U.S. that'd become a success is World Trigger. Meanwhile, the other three series, Bulge, Takamagahara and Cross Manage, all bombed straight away.
P.S. It blows my mind for Viz to be so reluctant for so long to release WT's volumes, and yet they were so much faster releasing volumes of all the failed series.
