Either side needs to be making factual and objective claims then. Slinging accusations of facism and retorting with the "you're the real facist" isn't going anywhere.
In practice there's probably no facism either way, but it's an easy and loaded term to throw around.
Then they'd be breaking the RFCs stated goal. The possibility of a stated ideal not working doesn't mean you shouldn't have the ideal. Though I suspect my definition of using fascist tactics likely differs from yours in this case, but this isn't the space to re-litigate the paradox of tolerance.
