I'm sure in a big city like that that there are lots of qualified people who give blood, however with "alternative life-styles," drug abuse, etc. being more socially accepted there than in most places, well, that should be a concern.
If you think our current "conservative" (yeah, right) Supreme Court is bad, wait until, God forbid, a Kerry Supreme Court declares that the "alternative lifestyles" folks and drug abusers have the right to donate diseased blood. That is not as far-fetched as it seems. Already some activists and academics are pushing for this.
