What if the telephone company doesn't want to carry your offensive message to your friend? It's a private company, the telephone company doesn't have to comply.

In other words, I don't think your analogy entirely fits here, as Reddit is more of a platform for communication, they're not paying an artist (baker) to create some art. Jus' sayin'

The telephone company actually does have to carry your message, because they are a common carrier and regulated by the FCC.

In other words, you argument is a bit ignorant. Reddit is a private forum that’s allowed to what they want as long as they don’t discriminate against protected classes.

Actually, in some cases, they do.

Internet companies have protection under the law that they can't be held liable for what their users say. IMHO that protection brings with it a duty to allow people to speak freely on their platform.

They can't eat their cake and have it too.

That law is already being eroded in this country in the name of child porn and sex trafficking.
