There's a concept that used to be popular in conservative circles called principle.
You say if FR gets to have over 1M conservative users Jim should lose the right to zot people.
The size relative to Twitter isn't relevant. Why should he lose that right if he gets to 1B users?
Oh, I fully believe in principles, and primary among them is to do whatever I think is best to protect my family, myself and my friends.
I think that should be everyone's primary principle, but you may think protecting evil nasty people who hate us and want to hurt us should be a more important principle.
There used to be a principle that you should always follow the law, and then people said slavery was such an egregious evil that we should drop the principle of following the law in an effort to eliminate slavery. They saw freedom for other men as a higher principle than the need to adhere to the law.
I say that if "the law" violates natural law, it is our duty to denounce it and oppose it until it is vanquished.
So yeah, principles are important, but getting them into the correct priority works best.
There is specifically, precisely, not a single word in Sec. 230 of the CDA as pertains to the 'size' of the website, its userbase, or its "Millions of communications" LOFL.
FR receives "Millions of communications" every month: scrapes, ddos attempts, pings, bounce-backs, and actual user activity -- if you could call this thread "actual user activity" -- if you don't believe me, ask John right here, if you think just maybe one of you could compose the question intelligently enough.
You know, on second thought, don't bother John.
