We live in a fairly solidly blue state, and my experience with the homeschoolers in the area generally reflect that. It seems with each passing year, more local businesses are cashing in on the homeschool community and it seems more mainstream. I get many more positive comments than negative ones.
I think the local religious homeschoolers form their own groups underground through their churches, etc. They probably aren't at the workshops on evolution or Norse mythology that we might attend. There are plenty of Christian homeschoolers that are doing it for academic reasons as well and seek out more secular venues.
Anyway, we are having a wonderful local experience homeschool. Down to 3 other families homeschooling within blocks of us. We are in St. Paul MN, bordering Minneapolis.
