Cory, it does seem worth correcting this. It's possible you saw some demographic data that separates 'mizrachi' from 'sephardi', which is a problematic distinction. 'Sephardi' may be used as a genealogical distinction, or an ethno-religious one. Both may intersect with 'mizrachi', which is geographical, and has an ancient meaning (east of the land of Israel, with Israel itself described as 'the west'), and a modern one (n.africa and w.asia). In contemporary usage, 'mizrachi' is most likely to be used in a political sense (suggesting an ethnic bloc), but less so biographically.
In any event, people with recent ancestry (on one side or both) in n.africa or w.asia do make up a majority of Israeli Jews at this point. None of this is to suggest a 'post ethnic' or 'post racial' reality, but it is important not to assume that familiar paradigms describe every situation. Meaningful understanding and discussion of the Israel Palestine conflict is often hampered by the wholesale import of such paradigms, both by those internal and external to the situation. Let's strive for accuracy.
Thanks for the link, the comics are cool!
