You fit partial denier, yes. The redditor you're describing would certainly fit into "post-collapsists" given that they are preparing for the collapse in order to minimize post-collapse consequences. I would say that most upper-middle-class+ educated westerners fit into the "partial denier" archetype, yes. It's in human nature to deny something bad is happening until its too late, and sometimes even then (see, eg. global warming, COVID-19, etc).
