Let them show "conclusive evidence".  Let them try to ban Bitcoin.  Let them vilify it.  Let them marginalize its users.  Let them fight it all they want.

And just as banning books makes them coveted, banning Bitcoin will only make Bitcoin stronger.

Anyone with half a brain can see the clear advantage of crypto currencies.  And realize they can't ban it anymore then they can ban email or bittorrent.

There is no appeasing that system.

There's no trying to abide by their rules.  Bitcoin & the current system of fiat simply cannot co-exist. 

The more Bitcoin users who openly speak up, the more of the lemmings will begin to realize they too don't have to bow to their masters any longer.

The more people speak up & opening challenge the corrupt & evil system, the better.

There is a way out.  Nobody has to bow to that system any longer.  The more who stand up & shout what everyone is thinking anyway, but too spineless to say it, the better.
