Talking of an inability to read posts, where did you see it in the topic about faeces on seats except where you wrote it? I also never wrote anything about your preference for babies on planes. What I did write was that some people, and I include you in this group because your own comments reflect it, aren't impressed with a naked and dirty butt in the seat next to them.
Anyway, and as I also wrote, this all really just needs to be put in perspective. You're far more likely whilst airborne to catch the common cold or headlice from your well-mannered fellow passengers than ecoli from a diaper change.
