In the end, Subway wasn't forced to do anything by anybody, so this "proves" nothing about Muslims or anybody.
And again, the only insinuation being made here, from The Daily Mail and from the name of the thread itself (I never said that there was anything more), is that this is in anyway new, that this is a sudden decision born out of the ether when it is not or that this is happening at all Subways when it is not. This has been going on for over half a decade so either people haven't caught on or there is something going on that warrants attention.
But on its own, this is nothing that should really matter to anybody. It is 13% of Subways where you can't a Meatball Marinara sub...well, one made of pork. Is this the start of a cultural revolution? Where our meatballs are made of turkey? EGADS!!
