This is not what I think at all and makes me sound closed minded (an assumption of the way I think). I did like your biscuit example though, 'cause it reminded me of how I began to like olives (oh man were they awful at first)!

As for techie parents, I had none of those. Every year I go home there is something computer related to fix. XD
My brothers played a lot of video games though, and I assume that's how I got interested in them. Was difficult to get my female friends to play them, but they did try.  I think Mario Kart probably garnered the most interest.  I like supporting Nintendo for this reason, as their target audience seems to be more inclusive in general.
