I'm really not offended. One thing I dislike about the internet is that everyone seems to think that just because you voice a counter opinion that you're ready to start hurling the rocks. And there really isn't a reason not to start a discussion about it when there are multiple sides to the issue. Car forum, internets, it's what they're here for. ;)
And, I'm not saying that it is something no one will ever need. I just don't see it being essential and don't want people to feel like they have to buy it when there isn't really any proof of that.
