Closeted Athiests??

im a muslim. well not really, to my parents and sibling i am. im a atheist and bisexual but my mom is OVERLY RELIGIOUS. like, shes anti-LGBT and thinks wearing black clothing makes you a "demon" and the absolute dumbest stuff like "sleeping with your chest down too much can make your heart drop and die" she got that from a friend. i cant even wear SKIRTS. the entire concept of a god just sounds stupid to me, id probably get kicked out of the house if i told her the secrets
