I've mellowed alot on Sinn Féin recently. I still won't vote for them, but I'm not as against them as before.
What I do find disappointing is that they seem to lack any sort of policy on the environment. The environment section of their website (which even pays prominent lip service to a united Ireland) deals with waste management (in a policy from 2001) and a movement towards local power.
There's nothing (as far as I can tell) on climate change, public transport, energy etc etc. I can understand to an extent that SF's focus lies elsewhere, but why is there virtually nothing? It seems fairly lacking for a fairly large party.
