I don't approve of sedition

I have little truck with Sedition, though I can be brought to understand secession. There is little beauty in the break-up of an established political union to search for narrow gain, though in certain extreme cases that may be justified.

However if said break-up is in pursuit of unjustified grievance, the upstaging of a union of equals through the subversion of legality, propaganda, and in the whole for the protection of a corrupt elite, I believe that case to be seditious. This is borderline treason.
The Oxford English dictionary categorises each with a straightforward definition:
Secession is;

noun
[mass noun]
•    the action of withdrawing formally from membership of a federation or body, especially a political state:the republics want secession from the union

Sedition is;
noun
[mass noun]
•    conduct or speech inciting people to rebel against the authority of a state or monarch.

Wikipedia takes the concept of sedition further in language, which is true and accurate and which I would not be capable of matching.

In law, sedition is overt conduct, such as speech and organization that is deemed by the legal authority to tend toward insurrection against the established order. Sedition often includes subversion of a constitution and incitement of discontent (or resistance) to lawful authority. Sedition may include any commotion, though not aimed at direct and open violence against the laws. Seditious words in writing are seditious libel. A seditionist is one who engages in or promotes the interests of sedition.

The only difference, in real terms, between sedition and treason, is the matter of violence and or aiding powers, foreign and internal, who run contrary to the established order.

I believe the Regional Government of Catalonia, (northern Spain), is engaging in activities which are close to, but not yet openly seditious by running roughshod over the constitution, denying basic rights to citizens enshrined in it, promoting violence on local government channels, running mass media campaigns that demonise the rest of Spain and it's peoples.

I hope it does not go further.
