Heterosexuality and homosexuality are subsets of allosexuality (sexual attraction and behavior towards others). Autosexual acts such as masturbation are not allosexual and so do not contribute to heterosexual or homosexual identity.
Example: A lesbian trans woman might masturbate using her penis, even though she has no attraction to penis-havers, just because she happens to be equipped with one.
Example: A heterosexual cis woman might masturbate using her vulva, even though she has no attraction to vulva-havers, just because she happens to be equipped with one.
Christian tradition teaches that we are the hands of God; that God gets things done in the world through the instrumentality of human action. When you do an act of kindness for your neighbor, you are instantiating God’s kindness; when you defend your neighbor from harm or oppression, you are instantiating God’s protection.
One of the big differences between Martin Luther King Jr.'s ideology of nonviolence and Mahatma Gandhi’s ideology of nonviolence is that King accepted self-defense while Gandhi rejected it. Dr. King carried a pistol in his early career, and was later defended by armed bodyguards; while Gandhi rejected armed protection and called for oppressed people to surrender to their oppressors. So empirically, rejection of self-defense is less Christian and more Hindu.
