as a believer in free speech which includes freedom to be mean and offensive
It doesn't, actually....unless there's a reciprocal 'right' to never return access to someone who wishes to be "mean and offensive".
The use of a Carriage Service to bully is an offence under the Telecommunications Act, which, being International is Federal Law.
I'm sure, however, if the relevant mods deem it appropriate you might be restored, assuming of course you understand the penalties that can apply when blindly adhering to your interpretation of 'free speech'...
