I think the discussion surrounds two issues right now:

1) Freeing the politicians. There's plenty of examples of politicians interfering in judicial decisions [1]. Currently, 45% of the Catalan electorate have their elected politicians in jail.

2) Discuss with the central government the best way to modify the constitution to allow a mechanism for people to vote for what they want.

I wouldn't consider myself an independentist, but being surrounded by people that are, I've come to understand that the biggest issue is whether they have the right to even have a vote on how they want to govern themselves.

As for the arguments for the independence of Catalonia, as other people mentioned here, there are several and as varied as people are in Catalonia. The first step though is to be able to even have this discussion in the form of a referendum, even if the final result is staying in Spain.
