I guess it depends on what it means "accepted"; my sentence is indeed ambiguous. Romans did not accept (like) the fact that Carthaginians sacrificed children.

I guess it depends on what it means "accepted"; my sentence is indeed ambiguous. Romans did not accept (like) the fact that Carthaginians sacrificed children. They did accept (acknowledge, which is a much better word here) the fact that children were sacrificed there. Some modern historians/archeologies did not acknowledge (nor presumably like) that at all.
