1. I did not start with optimism, the 'optimism' was in the post I was replying to which I judged from Catholic teaching to be 'presumption' rather than 'optimism'.
2. I didn't switch to hope. Hope is one of the cardinal virtues so it was intrinsic to the discussion which concerned presumption or despair of salvation and was absolutely relevant to the discussion.
3. Go back to no: 2.
4. I never mentioned pessimism once in my posts, nor did I endorse it or promote it.
I am glad that at last you finally concede that my comments were solely to point out that the general "after life" ought to be distinguished from the particular "eternal salvation". That was my sole intention several comments back.
