Everyone that's involved with bitcoin should ask some hard questions to any bank and/or payment processor that doesn't want to do business with bitcoin merchants.
Here are a couple of good links:

And although Bitcoin can be used for nefarious purposes, so can cash, sports cars, crow bars, sledge hammers, saws, scissors etc.. I don't see any of those being frowned upon at the moment.
And currently bitcoin is a magnitude of order smaller than any of these large banks. So, basically, if someone is afraid that they're going to be involved with parties that does criminal stuff, the traditional banks seems to be what should be avoided at the moment.
So everyone asking a bank or payment processor if they are bitcoin-friendly, should mention the HSBC and Barclays scandal, and ask them what steps they're taking to ensure that banks they work with are not involved in terrorist funding, money laundering, criminal activity and so on.
It would probably not help the slightest, but as the questions come in, perhaps it would knock some sense into those businesses not accepting bitcoin.
At least it should be interesting to see replies from those companies.
