I'm also quite skeptical of the "slippery slope"-style argument regarding IP connectivity. The number of available ISPs, web hosts, domain registrars, etc is pretty large. There are even web hosts that have an explicit policy of letting you host _any_ content you want as long as it's not against the law in their jurisdiction[0]. And they'll even host it on a subdomain of theirs, if for some reason you have trouble getting a hostname for your hateful or crazy (but legally protected from censorship by the government) blog. And if laws are ever made restricting what those web hosts can do, then we're getting into the realm of the government restricting free speech, which is a different conversation entirely.
Regarding your second paragraph, the right to "get heard" is not a right guaranteed to anyone, at least not in the US. If you are spewing garbage, no one should be forced to hear it.
(caveat: I'm in the US, so my opinions are US-centric)
