Education and transparency for me. More school tours of mosques and spread greater knowledge of how similar religions are.
This for me.
I'm old now but I remember when I was a kid and older people would use racist words, I never used to think anything about it. But as you get older you realise how wrong it was and so you teach your kids. If my daughter hears anything racist today she is horrified, this is all through education and teaching kids that we are all the same regardless of colour, beliefs or in this case religion.
It won't happen overnight but if we don't educate people, especially children, then our indifferences will remain and so these killings will go on and on and on.
I do wish the Muslim community would do more though, the silence at times like this is deafening.
Having said that, I've known loads of Muslims and spent years in the Middle East, I'm here now writing this, and I know for sure that they are as horrified by things like as we are.
I think it's worth bearing in mind that there are over a billion Muslims on the planet and a tiny tiny fraction of them are full of hate.
This is why I think that eventually education, combined with compassion and tolerance will eventually win the day.
By the way, I won't reply to any comments, not that I think anyone is right or wrong in their thinking, it's just that like most, I'm too angry to think straight.
