When seeking an attractive woman, I try to be colorblind. Actually, I pretend to be fully blind and use my hands to "accidentally" feel them like I am reading braille.
The ones that don't object are the best...no matter their race.
Try it sometime, but make sure you have your stick with you.
Not to use as a "blind person walking" prop, but to swing wildly when defending yourself from the unbelievers who lack compassion for your serious limitation
