Hoo-boy does this thread have the potential to get moved into the Tar Swamp. Politics, Religion, Sex and Flu Shots... the four most volatile subjects of today.
I'd like to give you my honest opinion, but I've witnessed how people on both sides of the issue like to come down HARD on dissenting opinions. And I have better things to do than have a heated back-and-forth with people less interested in informed debate than in quashing (and often ad hominem insulting) points of view that don't jive with their own.
So my advice is: continue to research the topic. Read articles from both sides. And then decide for yourself and your family. The older I get, the more I learn what should be a painfully obvious lesson: an internet discussion forum is the WORST place to go for information on divisive topics. The time you save is better spent watching MOTU re-runs.
