Am I wrong for demanding my son be removed from his teachers class because of her Facebook

I have a 7 year old son. He's in the second grade and has an IEP because he's mostly nonverbal autistic. I've always loved his teachers except this one teacher he has. I just got bad vibes from her. Another parent blasted her on next door because they found her Facebook and posted screenshots of some of her post. She was saying things like special needs kids is God's punishing parents for their past behavior. How she hates IEPs. Why can't they just keep all the r worded kids away from the regular kids. The one that hurt me the most is her having crying laughing emojis and is like "When you can say whatever you want to and in front of a dumb kid because they can't speak." I demanded my son be removed from her class. We received an apology through email but it was a shitty apology. It was basically "I'm sorry. I thought my Facebook was private." My son's teachers are very important to his development and if he has one that hates people with disabilities so much than I don't want him in her class.

Edit: I don't want to take away someone's lively hood. I just don't believe she should ever work with kids who have disabilities but I know how bad inflation is, and everything. I don't want to be the reason someone loses their way of living.
