Oh wow. Laura, you seem to be obsessed and your posts are screaming sarcasm to someone you don't even know.
It doesn't even sound like you're 'concerned' for Katie (shineyourlight). It's not just about correction, is it? It's more like a matter of pride. You know, fruits don't lie.
Anyway, it's good that you studied health and are sharing it to others. But when it's obvious that someone is learning it in a different way than you, and instead of helping, you're coming in as an attacker (you may be meaning well, but you're obviously not putting in effort to 'sound' well to the other party), how hard is it to drop a subject? It seems very hard for you. And it seems to affect you so much too and I don't think that is healthy.
The only thing you can bring to heaven with you is people, so be nicer.
