But, so long as we're not warranting the discrimination off ideas like *checks the last dozen pages*...

that Steam players are disproportionately WoW players, who must therefore be inherently toxic;
that Steam players' interests must be different because FPSs are sold on Steam;
that Steam players aren't as likely to appreciate MMOs because people don't go to Steam for MMOs, despite that accounting for a pretty significant portion of overall activity, downloads, and post-purchase transactions;
that any change in launcher is inherently a large enough change in itself to alter player perceptions of a given game; etc...

...then, that seems sensible.
So, we just ignore logical, reasonable arguments because we don't like that they effectively make what we desperately want to be true moot? *Curious look*
