Learning requires making mistakes. Kids need to learn social skills in low-stakes environments. School is the best environment for this. When a person misses this part of their childhood education, they may struggle to learn these skills later in life.
It sounds like you may be speaking from experience, and if so, I respect that.
My kids have done both public schooling and now homeschooling. For a variety of personal reasons, public schooling was not going to be an option for a couple of them, so we're trying this out now and it has been successful. We are tightly integrated into a very active church group, and they have lots of social interactions on a regular basis there, as well as opportunities with other homeschooled kids around town.
It's definitely a balance, and there's no one silver bullet on either side of the fence, but the best any of us can do is actively strive for giving each child the best and most appropriate experiences for them.
The ability to recognize sociopaths and manipulation is an important life skill which may not be obtainable at your church activities or with trusted families. People without these skills may be manipulated in the workplace and suffer avoidable career setbacks, stress, and attending health problems.
