'freedom-advocating' originates from the combination of 'freedom' and 'advocate', where 'freedom' means 'the power or right to act, speak, or think as one wants without hindrance or restraint', and 'advocate' means 'to publicly recommend or support'.

'freedom' and 'advocate' have been used in English since the Middle Ages, with 'freedom' deriving from Old English 'frēodōm' and 'advocate' from Latin 'advocatus'.

Initially, 'advocate' meant 'to call to one's aid', but over time it evolved into its current meaning of 'to support or recommend publicly'.
