Nappies, wipes and a banana are things you are likely to need nearly every day. The blanket you might put in the car and not need all winter. The two are not the same kind of thing - they are on the same continuum, but very far apart. Preparing for an emergency is preparing for something out of the ordinary and happens across all domains - some people's nappy bags will have rather more in than others, for instance, just like some people's pantries.
This board is just a handy place for gathering together the 'planning for the extraordinary' things from all sorts of domains of daily life into one place. Some people have a very holistic approach and are planning across many domains in an organised, joined up way, so they are either picturing either many scenarios, or a single much worse SHTF scenario; some people are picturing and planning for only certain isolated scenarios like snow. Either way this should be a good place to share information.
And Bertrand why do you care? You clearly don't feel this board is for you (since you said 'you are not preppers' rather than 'we are not preppers'). What's it to you anyway? Just the chance to tell someone they're wrong on the internet? That's rather how it's coming across.
