In the 6 years that we've been homeschooling, I've never had anyone react badly to the news that we homeschool. Some have given me question regarding the socialization of my kids, but then I remind them that the kids AND most teachers at public school aren't really the type of kids or adults I want my kids socializing with in the first place... at least not without my supervision. They have ALWAYS agree with that sentiment. 
Since the covid era, I've only received comments like "Good for you" or "Good job", or "I wish I could homeschool my kids.!" To which I always reply that they can. Most argue with me.  But even the many public school teachers that I know personally, know that the public school system is crumbling. It can't happen fast enough.  No one should outsource their children's education, if they can help it. There are certain circumstances where it can't be avoided. Public school is designed for those kids.
