This is the 21st century- and its far past time for us to treat others with the love, respect, and support we all need to thrive. Transgender rights are human rights. Treating them as such is the first step on a long road to deeper understanding, tolerance, and common humanity.
For the plethora of Christians opposed to such measures, I implore us all to find guidance in the call to love thy neighbor as thyself. Not understanding a sexual or gender identity is no cause for fear, but rather an opportunity to open our hearts in love, and allow those to speak and be heard who have for so long be silenced. Let us all humbly accept that we can’t know what it’s like to be transgender unless we are transgender - and let’s listen to those who know what they need to thrive and do our very best to provide.
This is not a question of policy or legislation, but one of love.
