That's called the internet.

Corporations having the right to censor is no better than the government.

Yes it is, there are lots of corporations and anyone can start one. There is only one government that applies to someone at any one time and they have a monopoly on violence.

In a common carrier world, the government censoring private individuals would go against our first amendment rights. Pretty clear cut.

It's clear cut that the internet does that already and corporations do not have to broadcast what they don't want to.

If you hate censorship so much why are you on hacker news? This is one of the most censored sites on the internet. Comments are not just deleted and removed but there is no record when they are.

There are plenty of sites that let anyone post whatever they want and they turn into people spamming nazi propaganda. You can find these sites and see if you like them better than the mainstream sites of the internet.
