Do you think teachers sending a kindergarten student out of the classroom is too harsh?

When I was working at a school before I resigned, there was a kid that would scream and shout at teachers when things do go his way. He would cuss at us and the teacher would tell him to get out. She angrily said, “Get out! Out of my classroom NOW.”
She would take him out and sit outside with him. Of course we would never let a kindergartner sit outside by themselves. So the other 3 staff including me continued the lesson. I asked the other two staff don’t they think telling a five year old to get out of the class is a bit harsh but they disagreed. One said, “No it’s not because one, he disrupted the class, two, he’s being disrespectful and three no matter what age, kids need to be taught a hard lesson. You gotta be tough on them.”
The teacher is one of the most sweetest most kindhearted people you ever meet but she isn’t afraid to tell it like it is and she is SAVAGE. She can get “mean” when it’s necessary and not afraid to throw that tough love and telling them to toughen up. She doesn’t put up crying or whining. If the child was really hurt then she will give them a hug. She is TOUGH for a little lady and she said she’s 4’11”. One time she called the kids out that I was shocked how “mean” and very stern she can get.
