This is a big problem which needs to be addressed in proper fashion. These people should be treated as though they are as honest as the next person, regarding this topic. They could be just as morally upright as your granny or most people of past generations who truly believed.
First, there should be recognition of the under-education that affects so many. This goes for people on both sides. Wrong ideas permeate through those “on board”, as well !
Next, no stumbling block should be placed for these people, so as to further the fighting or to induce a failure to accept.
As well, no heaping of scorn upon partial acceptance. No stumbling block placed that tells them they must bet their imaginary soul on a scientist’s “say-so”. ( denying god or their religion immediately, if they are really to accept Evolution as true)
Very important is that scientists do not give ANY false information which could be known to be untrue i.e., things about their own religion which they know to be false or wrong.
These things would help.
Any agreement with these points ?
