Religious symbols should be visible in public space, in a dignified and non-provocative manner. Christmas trees here, Jewish menorahs there and, further along, a minaret - these symbols represent human life in all its diversity.

Muslims must speak out and explain who they are, what they believe in, what they stand for, what is the meaning of their life. They must have the courage to denounce what is said and done by certain Muslims in the name of their religion.

There are clearly many good politicians who are guided by religious belief, so the mix can work. But there's a line to be drawn. It would be hugely dangerous for a country's laws to be set by the scriptures, and particularly those of the expansionist religions.

'Skyline' is an alien invasion film that really takes an interesting look at the genre. The writers did an amazing job of creating a new take at how life from other planets come and plan to invade Earth.
