I have not seen any direct quotes from Issak Wolfe (Sierra Stambaugh), so it is not apparent what the personal wishes of this young person actually are.
I would like to caution Issak not to allow manipulation by those who seek a gain for their own cause or causes. It would appear to me that the Red Lion Area School District is following current standards by using everyone's legal name at the graduation ceremony.
Equal rights are not special rights.
Perhaps energy would be wiser spent seeking modernization in the legal name change process itself, rather than badgering the school district for following current rules.
What seems to have turned into a public temper tantrum (toddler behavior) because of not getting your way, despite nothing illegal occurring, only lends credence to the idea that high school pupils are indeed not mature enough to make the type decision you are about to make.
