> Free speech is a cultural value says that controversial speech shouldn't be censored
No, free speech (and the related freedoms of press, religion, and association) is a cultural value that says every member of society should be free to choose which ideas they will promote and which people they will associate with, applying their own values.
That absolutely includes choosing which ideas from other people they will participate in spreading, which, yes, is censorship (but not public censorship), but remains absolutely central to the ideal of free speech.
Freedom of speech is not entitlement to have others cooperate in spreading your speech.
Wow! What's up is down and down is up. I assume you are vehemently on the side those wedding cake bakers who refused to make a gay wedding cake, then?
Once a private communications provider becomes recognized as communications infrastructure, they lose the right to police content that goes through their infrastructure. For example, my ISP, even though it participates in "spreading" my ideas, has no say in the matter. If you can argue that some random wedding cake bakers are part of "critical wedding baking infrastructure and must therefore be compelled to make a gay cake," you can argue, much more easily, that Cloudflare has no business deciding what content it offers its services to.

The issue of limited discrimination protections on specified axes for public accommodations is a thorny one especially when it comes to expressive acts; there's plenty of room for debate on what axes should be protected, but a general non-discrimination rule for political ideology has never been seriously suggested, and would arguably run afoul of the first amendment.

That's not the legal basis; a specific protection from sexual orientation discrimination in public accommodations (in state law in the state in question) is.

Then I guess you're in favor of passing legislation to this extent, right?
