I would never support the government throwing Alex Jones in jail espousing his views (Assuming we're not talking about edge cases where freedom of speech does not apply).
But I also fully support the property rights of Twitter, Facebook, etc to exercise control over the content of their platforms.
You wouldn't permit someone setting up camp on your front lawn, passing out, say, NAMBLA literature would you? It's unlikely you'd say "Sir, I do not like that that you are on my lawn evangelizing man-boy love, but it's your god-given right to do so!" -- you'd probably (rightly say) "Get get the F--- off my lawn!"
Your property, your rules.
