So I was debating this with a friend earlier,
If you one day need a life saving operation, which requires you to have a blood transfusion etc. Should you be given the blood if you have never given blood before?
(Excluding people not of age in your respective country e.g. minors)
EDIT
Also excluding people who can't give blood, for example some of the ones mentioned,
Men with male sexual partners
Anemic
Also keep it on topic, examples like these that were posted...
Should anyone who isn't a lawyer get legal aid?
Should anyone who isn't a chef be allowed into restaurants?
Should anyone who isn't a game designer be allowed to play WoW?
These are business's and not a life / death situation which the topic is about, tbh
