The original thread was about terror attacks in Tunisia and France, but somehow the enormity of the deaths of so many, seems to have veered off into a counter argument about colonialism and disaffected people who don't like living in the UK as if that somehow mitigates these awful events.
I don't know whether where we live affects how we react, I live close to London both my children work up there. I worked up in town myself during the whole IRA campaign and yes it can make you twitchy and paranoid. I'm not sure someone living in say rural Wales could understand that, some areas are pretty safe, I'd never say never, but I think it's unlikely terrorist would target a gathering in a church hall in a rural village anywhere when they could pick off so many "decadent" young people at say The Ministry of Sound, a proposed target a while back. I'm sure an atrocity taking out great numbers could be committed in any urban area up and down the UK, after all didn't the IRA kill people in Warrington I believe, not an obvious choice. Nevertheless, London and other major cities will be prime targets as demonstrated by the 7/7 bombings, I happen to know someone who was caught up and injured then and that has shaped my feelings to an extent.
I don't buy the argument that somehow killing innocent people is understandable because you aren't having a very nice life here. Some of those Jihadis were doing more than OK in the UK, they weren't all living in impoverished circumstances by any means, there are privately educated pupils there, medical students, university graduates and they happily took what this "horrible" country had to offer. I dare say some of the Londoners that went possibly frequented clubs and establishments they would now like to blow up.
Marching for peace and against fear, whilst commendable, is futile unless those who wish to randomly target us in terrorist plots take notice of all of you on those marches, or is it just aimed at only far right fascist and not also the fascists that make up ISIS, because they are spreading more hate than just about anyone at the moment. We are hardly likely to get "peace and love" all round if we know that we are an ever present target for mass murder. A march to resonate with most would need to include the denunciation of fascists across the spectrum and that would include those who are sympathisers of the Islamic State. Lets not forget a terrorist bomb is a threat to all manner of people, particularly in a cosmopolitan city such as London, as 7/7 demonstrated.
BTW I do think sections of Irish were put under the Police scrutiny in areas such as Kilburn where Irish communities were prevalent, when the IRA campaign was at it's height. The main difference between the Muslim threat and the Irish one was that the latter was sectarian and pretty much confined to Northern Ireland and main land Britain, but nevertheless I think some Irish were viewed with suspicion, possibly rightly or wrongly. The ISIS threat is more high profile and global. In any case I don't ever remember a declaration once a bomb had gone off along the lines of "that one was from Pope Paul V1 or it was the will of Jesus Christ" There wasn't such a pervasive threat from them, insomuch as their wanting to replace our way of life with something brutal, subjugating and inferior.
