We can only use our best judgement when supporting political groups. The "Real IRA" has been publicly denounced by both the Provisional IRA and Sinn Fein (and just about every political group in Ireland). Should Sinn Fein or the IRA ever support this group, they would lose my support.
It's just like when you or I pay our taxes. We can only trust that our Governments are putting that money where we want it to go.
Yes I will continue to support Sinn Fein and the PIRA. However I will never support attacks on Irish or British citizens. Both the British and the IRA have done things that we can't support in the past, but hopefully the Good Friday Agreement will be put through and the peace process will continue despite the attempts by common thugs targeting children to thwart the progress.
