Nope as I explained in the post you quoted - saying I do not think it is or was acceptable "is a different statement from saying human sacrifice was never acceptable as that becomes more than just my opinion in 2019."
But all you and I are doing is providing our opinion on the moral acceptability of certain actions. Neither you nor I are in a position to go beyond that - neither of us are absolute arbiters of objective morality (even were that to exist).
So it seems to me that:
Your opinion in 2019 is that human sacrifice is not acceptable (i.e. now) and was never acceptable (i.e. in the past).
And,
My opinion in 2019 is that human sacrifice is not acceptable (i.e. now) and was never acceptable (i.e. in the past).
We are in agreement. And presumably we both think that people, who in the past, considered human sacrifice to be morally acceptable to be wrong.
So I think your statement that human sacrifice was never acceptable is an incorrect statement.
No, because it relates to my opinion (see above, which is the same as your opinion), the result of which is that I consider that people in the past who thought human sacrifice to be morally acceptable were wrong in that thinking.
