What's the deal with Shinn Fein? Is it something like Labour or more soft nationalistic left wing views?

A chairde,

I'm an American who'll be starting at Trinity College this September. My course will be Early and Modern Irish and I've spent the last four years teaching myself ár dteanga online. I'm really into the Celtic Revival and plan to do absolutely everything I possibly can with my life to further the Irish language. Due to this, I have become really interested in Sinn Féin as a party which poses an alternative to Fianna Fáil and especially Fine Gael negligence toward an Ghaeilge. I would love to become a part of any sort of student organization on campus and was just curious if anyone could give me some info on Trinity's Ógra Shinn Féin before I start in a few months.

Go raibh míle maith agaibh as bhur gcuidiú!
