why? should our opinions be based on entirely on what is at our doorstep. You seem to have strong opinions on people you have never met.Do you live in an area that is heavily populated with migrants?
I have lived in multi-cultural areas. Not had much trouble there. Lived in an area growing up that was pretty much exclusively white and been threatened with violence and attacked on several occassions. I am tolerant enough to know though that there are non-white areas that have problems with violence too. which is why I prefer a mix.
Just out of interest... has it occured to you that not everyone on here is white and that some might be Muslim. Are you willing to discuss this with someone who is Muslim and hasn't committed any offence in their life? Not getting at you. Just think it may be a more enlightening conversation for everyone
