No, it doesn't. If censoring mining pools have 51% of the hashrate, then they can permanently exclude any transaction they wish. If a normal mining pool mines a block which includes a "blacklisted" transaction, then the censoring mining pools with a majority of the hashrate can simply ignore that block and re-org it out with 100% certainty.
That's a '51% attack' isn't it, could it be that easy for the BTC network to move from censorship resistant to censorship, because that's what it means if what you said above happens. I don't know the total hashrate controlled by censoring mining pools, but i think individual miners would withdraw from censoring mining pools if it ever gets to this point, that would surely reduce the hashrate they control.
