Not ignoring anything.
The prohibition against eating blood was established BEFORE the old covenant was given. So even in a covenant change, that would not be effected.
And it WAS reiterated at the Council at Jerusalem after the new covenant was in effect so it still IS in effect.
Do you protestants eat fat or not?
Further it doesn't matter because like I said NEW COVENANT, NEW RULES!
Jesus said it, I believe it, you are the ones saying Jesus lied.
