This is a major reason (but far from the only reason) that we homeschool. Knowing what I know about the school system, about my own experience thereof, and about my kids' personalities, it would be grossly immoral for me to put them through it. The risk of long-term trauma would be too high.
There is some risk of their being isolated (but very low, since they are with other kids three days a week), and a slightly higher risk of missing chunks of learning (which we aim to mitigate in the obvious ways). But ultimately I'd rather my kids have a few gaps in their knowledge than be traumatized by the school system.

I went through a normal school system (the first 8 years still during the communist regime in my country, so take that "normal" with a grain of salt), and the gaps in my knowledge are enormous, in some cases subject-wide. I know literally nothing about chemistry, except the bits you learn here and there from TV shows and such. I vaguely remember some kind of equations, but nothing stuck. Biology - everything I know I know from somewhere else, mostly from that TV show with talking blood cells [1]. Surprisingly, I had pretty good grades, but it had nothing to do with knowledge - I was able to quickly scan the textbook before an exam and somehow it was sufficient, but there was no retention, I forgot everything after the exam. I was forced to learn Russian for 4 years and I remember literally nothing, not even the alphabet.
Those are mostly just anecdotes - I am sure that modern schooling can do better than rote memorization in a toxic environment. What I want to say is that motivation, a friendly environment, and fun learning are a lot more important than how well the teacher knows, say, chemistry. It is entirely possible that your kids will retain more knowledge, not less.
I am only talking about elementary school, college was different - I loved it and learned a lot.
