I agree with Cardinal Farrell. The Spirit led Pope St John Paul to say that the divorced and remarried without annulment should not receive Holy Communion then a few years later because of today's changed society the same Spirit told Pope Francis that they now could. Why would the more liberally-minded not agree with that? 
Chrizmart has already pointed out that the Holy Spirit doesn't just speak to conservatives, He speaks to liberals too otherwise He wouldn't be egalitarian.
