Purify with the sacred flame brother Mathias.....

Do you guys feel the same about Walmart, McDonalds, etc?
Why, does Walmart and McDonalds attempt to double spend Bitcoins and execute a 51% attack on the network?

AFAIK CEX.IO/GHash.IO hasn't launched an attack on BTC, nor expressed any such intentions. I can't speak to the double spending, other than to say it doesn't make sense for an exchange; Mt GOX implosion scenario, et al.
RE: Walmart and Mickey D's; both have been accused using their enormous market share to drive smaller competitors out, through under-pricing; a fiat currency 51% attack, if yo will.
I haven't heard calls for burning Ronald McDonald at the stake, nor expressions that its good to die opposing the construction of a Walmart. Why such rhetoric for CEX.IO/GHash.IO? Seriously.
