Not to disagree with what you've said, but JT's Stockroom (http://www.stockroom.com) is one exception that proves the rule. Their home page offers a link to their hetero site alongside a link to their homosexual site. Some businesses can and do cater to a specific segment of the market, sensitive or no.

The Payment Card Industry (PCI) POS Pin Entry Device standards set by Visa/MC/JCB specifically require that a device used for credit card transactions NOT store the PIN and be resistant to tampering (such that a card holder would be able to see that something is wrong with the device if it had been tampered with). Merchants are required to use devices that have received PCI certification through a certified testing lab. It would be interesting if these devices have received that certification.
