The Freedom Of Speech Paradoxes & Their Logical Alternative

Premise 1: If a statement contradicts itself then it disproves itself. If a statement doesn't contradict itself then it is more likely to be true.
Premise 2: All three current positions regarding freedom of speech are self-contradictory:
A) Supporters of Freedom of Speech who say, "Freedom of speech is good so DON'T criticize it" are saying something paradoxical.
B) But critics of freedom of speech who say, "Freedom of speech is bad and I want the freedom to say that" are also saying something paradoxical.
C) Thirdly supporters of freedom of speech who say, "Freedom of speech is good so DO criticize it" are also saying something paradoxical because they're saying "X is good so say that it isn't good".
Premise 3:
Is there a non self-contradictory position about freedom of speech? Yes, there is.
"Freedom of speech is sometimes good and sometimes not good".
Conclusion: The position, "Freedom of speech is sometimes good and sometimes not good" is more likely to be true than the previously stated positions.
