Firstly, I'm a believer in the rule of law, not the rule of the mob. What these two individuals did in Woolwich was the latter. If we all take the law into our own hands, this country would be like Syria or Somalia which I'm sure none of us want. Would you really want to be taking your life into your hands everytime you go out to buy a loaf of bread or a pint of milk?
The Nazis tried in Ukraine killing 100 locals for every german soldier killed by the partisans. This did not stop the killing of German soldiers, in fact it increased it due to the feeling of injustice. After their defeat at Stalingrad many German soldiers tried to escape through the Ukraine, but very few made it back to safe areas as the partisans took their revenge on the killing of the innocent civilian population. Where many Germans thought they would be safe going through woodlands, the opposite was true as that was familiar territory to the partisans where they hid and lived in them. Such action on innocent people of any community would leave many people quite rightly aggrieved. I certaining would not want to see any such gross injustice to any members of UK society.
99.9% of Muslims are law abiding citizens that like you and me want to earn a living and bring up or be part of their family. Attacks on such people and their Mosques is again the rule of the mob and must be condemned. If not, where will it end, the killing of innocent muslims, which would make us as bad as the terrorists in Woolwich.
I think that there is a problem in society where only a white man can be racist and this does need to be addressed. Likewise, the free to exploit attitude of the authorities to vulnerable white girls by Asian gangs. But it both cases it is the politicians and authorities that need to get their act together to address these issues so there is a level playing field in the eyes of the law for all UK citizens regardless of colour, creed or faith. Good law is where all people are equal in the eyes of the law. Sadly, IMHO there have been many bad and misguided laws passed in the last 15 years. This was not a problem before 1997, nor was the expelling of undesirable people back to their country of origin, where it was against the UK national interest for them to be here.
For society to work we all have to obey good and bad laws. This means the laws we like but also the laws we dislike as this is the only way society can work in a civilised way.
I very happy with a reasonable levels of immigration as I think this has added to UK society, but I don't agree with the mass migration that has happened since 1997, but we can't turn the clock back, we are where we are. The Conservatives are trying hard to stem the tide with some success, but if like me you don't like our current society on many levels, then either make the effort to change it through peaceful political activism or like me decide to emigrate to where you feel more at home. I'm not alone 1,000,000 people that were born here have left in the last 10 years, mainly people with international in demand skills.
