one stands up for one's rights or one has none.
Yes - you know that from history, from the civil rights movements, from the Oz union movement, the ILO and a thousand more examples.
Every day you need to ensure that your rights are protected or you will lose them, through legal machinations, through 'lurve', through 'benefit of others', 'commnon good', 'homeland protection', 'economic recession' etc etc. Any time one human being has any level of power over any other living thing, then rights are in danger unless there is vigorous defence of them.
We've also moved away from the cultural and onto the individual - individual unconsciousness, mystery, diversity works, because we relate or not relate on an individual level. Hero worship of the eccentric, bullying of the weird. But when you are ascribing an unknownable 'alienness' to a group you are ensuring barriers are kept in place, that 'our group' retains the capacity for 'dehumanising' that 'alien' group. We retain the power of saying - they are not like us, they have this 'culture' that can never be changed, they will never fit in with us - and therefore it doesn't matter if we annihilate them, we don't have to think of them as being 'us'.
Historical and current examples abound.
