Say what you like about the south, but we don’t have this garbage going on. I would know about it, I work for a public school. Where did this happen? The link was frozen when I tried it.
About four or five years ago, we were read an instruction from the county at a faculty meeting. Teachers and staff are prohibited from discussing their sexual orientation, of others and particularly that of the students. There may have been some exception in discussing the students orientation with school psychologists.
In the interest of full disclosure, I do have to say that our high schools do allow lesbian gay alliance clubs. But that is high school. We don’t allow that in middle school on down.
