Here is why I am a humanist:
Any time one's morality is based on a religion, then the deity of that faith system is the highest priority in determining right and wrong. If something "hurts" or offends the deity, then it is wrong, even if it hurts no people. If something uplifts or glorifies the deity, then it is right, even if it hurts people.
In humanism humanity is the priority. We also value animal and plant life, and even the "life" of the planet and universe, but humanity is the focus. If it hurts people, it's wrong.
Furthermore, religious morality (sometimes subconsciously or unintentionally) gives priority to people who value or align with the deity. Humanism gives priority to humans who value humans. No label (race, gender, religion, orientation, etc) changes that value.
I don't have a problem with your religion. I have a problem when any religion becomes a weapon against other humans.
