They are trying to legislate haircuts. From the article: "The bill defines "social transition" as: “The process by which an individual adopts the name, pronouns, and gender expression, such as clothing or haircuts, that match the individual's gender identity and not the gender assumed by the individual's sex at birth. Teachers found guilty of “supporting social transition” would be placed in the same sex offender registration category as Tier 1 sex offenders, which is Missouri’s lowest level but includes possession of child porn or attempting a sexual act."
Telling a kid it's ok to have a particular hairstyle or clothing is going to be equivalent to possession of child porn?
