Also in plenty of small towns that is already the case - people in coal country get ruined if they complain about coal, or the mining companies. Which is considered legal.
But let’s put up a very simple example: if I rent out a billboard on a building I own, should I be required to post advertisements from a political candidate I disagree with? Your interpretation of free speech says yes I should have no choice, likewise if I get a pro-hitler or pro Stalin, pro genocide, or pornography, I have no choice I just display it.
Actually here’s a very American example: during elections people stick the little plastic political boards in their front yard, in doing so they’ve declared that their front yard is a space for political ads - should Someone then be allowed to put opposition ads there as well?
This is your definition of free speech: if you publish any speech, you are required to publish all
Please don't pretend a problem doesn't exist, because you disagree with one of the possible solutions to it (or an extreme caricature of such a solution that you made up on the spot).
I didn't give a definition of free speech (neither its spirit nor the law establishing it). I merely gave an example illustrating how farcical it is to ignore all factors except the government, when evaluating the degree of freedom of speech that people enjoy.
