Diseases in recently-infected blood can go undetected. So all potential donors are screened for activities which may put them at risk from infection.
I agree with this.
On the hooker question I think its personal decision and only 'technically' a lie. barebacking rundberg chicks, vs protected sex either with an escort or some college cutie on 6th street is the same risk in my eyes. heck probably less. I think it just saves them time to lump it all in one question instead of asking 20 questions. Did you pay and wear a rubber, how drunk was she, etc etc. It does pose additional risk to the bloodsupply, but if the rubber doesn't break I am ok with telling one more little lie amongst the other bazillion little white lies we say on any given day to get through society.
p.s. acupuncture doesn't disqualify you at all

I think there is more science than social fear in this.
