Question

Donating blood—no, because unlike in the past they don’t write the father’s and mother’s details, and make do with a name and ID number, that is, may they be delivered from such things.
But receiving blood, if it is definitely needed—yes.

That is: as part of a kind of struggle, a group declares that it will take, yes, but give—no.
And this is with blood. A life-giving donation from one person to another.

Could this lead it in the direction of systematic exploitation, in a process that is only just beginning?
Something similar to Haredi society?
