As Pickles says, one man's freedom fighter is another man's terrorist.
To my eyes McGuinness was a ruthless murderer who became part of the peace process, which could never have happened without some of the men of violence getting on board. It turns my stomach some of the things which had to be done to achieve the peace, such as releasing convicted murderers, but it was necessary for the greater good. The only bit I'm struggling with these days is the continuing persecution of service personnel for what went on, while the page has been turned on all the terrorist atrocities.
Thank you for saving me the trouble of writing what I was going to write.
