If you want to see a real percentage of the people want to leave check the votes, not a referendum that was only favoured by one part, thats why it was 90%.

Last elections and past elections was below 50% if I remember correctly, with PSOE and PSC (catalan socialists from PSOE).

Sanchez is as vile as you would like, but actually now is in negotiations to stop prosecution and do an amnesty, I think you haven't followed news since 2017.

And honesty, indepence within modern democracy is complicated because the country belong to everyone and no one, is public. You cannot take your part of the state (Elon Musk style...) and expect other people being ok with it so easily.

And sorry, they are not opressed in colonial manner, they have representation, language, culture respected by the constitution as laws above all, and the same rights as all citizens in Spain.
