Religion is definitely not an immutable characteristic - there are many ex-theists, and people often change religion on marriage. Gender is a can of worms - sex is immutable, gender seems to be (like religion or race) a socially conditioned performance of expected behaviour. Personally I don’t think it’s helpful - we should see ourselves as unique individuals with agency - much less immutable.
