"Tolerate all speech..."
...the next word is "that", a qualifier. And that qualifier answers literally all your questions?
There is no successful formulation of absolute free speech, because then you must allow intolerance, which takes over. This isn't a new question. https://en.wikipedia.org/wiki/Paradox_of_tolerance

Let's apply my test: What happens if someone's religion mandates intolerance? Then they are violating the social contract of tolerance--we should not allow that to be done.
> a religious Christian/Muslim/Jew would advocate for the removal of you for denying their right to speak their minds.
They can speak their minds about anything they'd like, so long as they don't advocate for the suppression of the rights of others. That is the thing that is not allowed. Their right includes that qualifier; it is not an absolute right to speak. This qualifier is the safety net that stops a tolerant society from being eaten by intolerance.
(I am not saying that free speech as outlined in the US constitution, for instance, meets this formulation from a legal standpoint; I am saying that social mores do and should, and certainly private speech and private platforms should be formulated in this way.)
