Of course they don't. A good proportion are even likely to believe that 'death' may be potentially ' a preferable state of 'being'. (Consult the latest atrocity news if in doubt). For them 'fear of death' is irrelevant. That why we cannot argue that 'suicide figures' mitigate against 'fear of death'.
The whole point is that this thread is about fear
of death. It is no consolation to those with that fear that others
do not have it. IMO it is better to point out that they
themselves are already familiar with a state of 'loss of awareness' every time they enter dreamless sleep, or undergo general anesthesia. Religious palliatives may be additionally therapeutic for obvious reasons, but I admit to raising that point in anticipation of your own possible fallback position given your posting history.
