You fundamentally miss the point.
You assume that an authority, "allows" you to speak.
That a platform will be "given" to you.
A privilege. Which can be removed for "naughty" behavior.
Value judgements, performed by a legitimate authority upon a subservient subject.
Look at you, willing peasant.
Kneeler.
Faced with those, with different views.
Ridiculous, abhorrent, trivial, mocking, insightful, provocative, ...
What do you do?
You call them scum.
Belittle them. Mock them.
Ban them.
Well, it did not work against the National Socialists, nor against the Bolsheviks.
Should you really be a liberal, or a progressive, then you would appeal to reason, to debate.
You would seek to convert those in the dark, to your light.
But you don't.
So you are no liberal.
Why should then you have the right to speak, when you deny it to others?
Rights are indisputable, and they include the Rights to think, speak and listen.
