I don't agree. I think that more icing accidents have come from takeoff attempts with inproperly deiced airplanes. The past decade has seen significant improvement in deicing technology (Type IV fluid), procedures and awareness so that should be improving. Most inflight icing accidents are on smaller airplanes, not airliners (jet or turboprop). There have been some exceptions, particularly the ATR, but that was blamed on inadequate design and training which has now been corrected.
Once in the air, transport category aircraft can take care of themselves in all but the most severe icing.
