It is a transphobic bill that blocks all age and medical appropriate gender affirming care for a person under 18. This includes totally reversible actions related to social transition including name changes and clothing choices.
Have you read a summary of the bill? As far as I can tell, it specifically pertain to medical procedures and therapies. The activist article you linked mentions clothing and names as being things children may change when they see themselves as being transgender, but these certainly do not seem to be things prohibited by the bill.
I did read the summary from the HRC (the largest LGBTQ lobbying group in the US, btw). I also decided to bypass another summary to read the text of the bill, which explicitly bans social transition by disallowing:
(1) Enabling a minor to identify with, or live as, a purported identity inconsistent with the minor's sex; or
(2) Treating purported discomfort or distress from a discordance between the minor's sex and asserted identity.
(a) A healthcare provider shall not perform or offer to perform on a minor, or administer or offer to administer to a minor, a medical procedure if the performance or administration of the procedure is for the purpose of:
(1) Enabling a minor to identify with, or live as, a purported identity inconsistent with the minor's sex; or
(2) Treating purported discomfort or distress from a discordance between the minor's sex and asserted identity.
You are missing that clothing and names have really nothing to do with gender outside of society imposed social concepts and that children should be allowed to grow up in the bodies they were born in and not made to feel alienated from their own selves to the point of self mutilation.
