Conflicting thoughts

So recently I got the papers to register peanut for kindergarden. My thoughts are that I am not ready to have him gone all day in a school setting. I want to home school my husband says no. Where do I go to find supporting information to home schooling? Facts numbers etc that show my husband that peanut is not going to end up a sheltered unsocialized child? Help me out. Post some links for me of legit sites that he can read up on. I guess I don't really want the school system raising my kids I want to do it. One of the most alarming things that I have read so far is that home schooled children only need 2 and a half hours of instruction a day. What are they doing the rest of the time they spend in school??? I'll write more later I just wanted to get that off my chest!
