People often don't like if you make a decision which is different from theirs. They sometimes take it as a message that they must have made the wrong decision themselves.
I think this pin points a lot of tension and angst in these conversations. In general, when someone asks, what they really want to hear something that isn't contrary to their own choice. I do my best to explain our decision as being solely about US. And not the school, etc. There are those cases (in the grocery store, etc) where you really don't care what people think. I do come across needing a better explanation why we're homeschooling pretty frequently though.
