>the words on this print out sufficiently state all are welcome

If all are welcome why did Hanover seek the ADF's review of policies regarding trans students? Hanover refused to adopt policies that allow a trans student to use the bathroom that aligns with their gender identity. And then they go and seek the opinion of ADF which has goals of "ensuring the law respects God created order for marriage, the family, and human sexuality.”

Are the words enough? No. Not when Hanover is seeking input from a group that doesn't see trans rights as human rights. Not when Hanover's school board has to individually approve which bathroom a trans student can or cannot use.

Edit: I did notice in your original comment you mentioned how you didn't feel the need to be in "battle mode" all the time. I don't know you or your political ideology, but trans people are continually being targeted by Republicans and the alt-right every day.
