Yeah, I think of our kids and how my wife feels about what they are being taught at public schools. The schools in our area do not officially celebrate the holidays due to their being politically correct with all the religions (remember the Jehovah's Witness religion is not the only religion to not celebrate Christmas for example) which I actually agree with but they still do some things related to the holidays. My kids come home frequently with Mother's Day cards, Christmas themed crafts, etc. not to mention the interaction with people of other faiths.
If you want to get a glimpse of what witness children will be like if everyone turned to home schooling look no further than your other fundamentalist sects who advocate it on a whole. Look particularly at the quiverfull movement (http://www.patheos.com/blogs/nolongerquivering/) at the sections that speak about homeschooling.
