Take a step back, stop being so defensive, and realize you are wrong and you can actually learn something. You seem to care about this, so take it as an opportunity to actually learn what free speech is and what you can do to protect it.
Free speech is not some idea by which all companies much publish all content with an equal hand. That's an absurd standard. That's actually antithetical to free speech ideals, as it FORCES companies endorse speech that they, themselves, don't agree with.
> To repeat my previous point: assume the same law was passed in North Korea instead of the US. Would the law then be "not a violation of Free Speech" because North Korea has no legal protections for Free Speech?
Of course it would. It would be in the US, and it would be in North Korea.
North Korea is a great example, and it's not hypothetical. But in North Korea it is illegal for anyone to be critical of the military—not just asking certain publishers to be more selective about what they publish.
But none of this has anything to do with Cloudflare. Cloudflare is just a business. It's a non-essential, privately owned company that has nothing to do with the government. If someone from 8chan goes into the local Starbucks and starts screaming about killing Hispanics, Starbucks can ask them to leave. That's not a free speech violation.
If this was something like ICANN seizing a domain or the FCC refusing to issue a radio license you could at least make the "slippery slope" case with some kind of loose validity. But we aren't even talking about that. No one has to support your speech. Dell doesn't have to sell you computers for your server farm and Cloudflare doesn't have to sell you CDN services. CNN doesn't have to give you airtime, and Amazon doesn't have to publish your book.
You can build a horrific media empire that endorses and promotes the most disgusting and hateful forms of speech imaginable, but NO ONE has to support you in doing that. And, in fact, no one SHOULD be forced to.
Just look at Alex Jones. No one has arrested him (minus an incident in New York with him literally screaming into someone's face with a megaphone, which was borderline assault) and no one should. But no one has to support him either.
