Fist time posting and not sure if this fits in here please let me know if not and will lose and reopen in correct area.

Firstly a bit of context for why I am posting my question before citing it. I live in France where religion (or lack thereof) is taboo in general conversation so have very little experience of debating or discussing topics and obtaining first-person religious viewpoints on most topics and what little experience I have is limited as the conversation tends to be quickly shut down.
I was hoping therefore to obtain at least some second/third hand understanding of a particular topic.

The topic in question is relating to the differences in views on death and, more specifically, fear of death between atheists and theists.

From personal observation from reading in forums and watching a number of debates there appears to be a difference in how afraid we are to die based on whether we believe something will happen to us after death or not and there is a difference in what we will accept to avoid death.

My observation/hypothesis is this, atheists are not as afraid of death as theists are.

Now this is a highly generalized observation so I absolutely accept that there will be individual incidences where this is untrue and also is entirely based on my own personal observations so I may have completely misread and be completely wrong (especially since it doesn't entirely make sense) .

The specific example, which crystallized this impression, was from a forum post on a different subject where the conversation had turned to Christianity's God's support or lack thereof of women's rights and a particular discussion around Deuteronomy 22:28 in which it was posited by a theist, and agreed to by the rest, that being forced to marry the rapist (at this stage of the conversation both sides had agreed that this was what the section referenced) was better than starving and being ostracized (and therefore dying) whereas each and every atheist declared that considering the trauma and psychological damage involved that the opposite was possibly a preferable option in those circumstances.

I am simplifying for the case of the question and have added the link above for the full conversation if complete context is needed.

So to my question is my observation accurate and if so why? As it seems rather counterintuitive since if there is a "heaven"/"reincarnation" why would someone be afraid to die?
