As you pointed out, Schools make their own rules about what you can and can't do. And, they're completely within their rights to also impose consequences for breaking those rules.and, just like a workplace, schools will have rules about what you can and cannot wear, say, or do. That's just how it is.

I agree with you this amendment argument is ridiculous. The children are being sent home for refusing to follow a school rule. In my high school, we had a rule that you weren't allowed to eat food on the second floor. If you refused to follow that rule, you could be suspended. It's really no different.

My response to the article was somewhat off-the-cuff and not meant to be taken seriously. It was more of a response to the bit where the kids mentioned that they would be fine with a schoolmate coming to school with a shirt saying the same thing about Christianity. if they feel that way, they should have no issue wearing such a shirt in support of their peer's rights. Sort've a "put up or shut up."
