Fallacious argument. Would you also be opposed to people dressing as say...goths, or clowns?
Is there an Australian way to dress? Or 'not dress' rather? Do you see where I'm going with this?
The home grown terrorism in France is linked to a few factors, including, but not limited to:
- Large ('legal') Muslim population that has been isolated and discriminated against.
- Aforementioned population largely of low socio-economic status.
- Capitilisation by Wahabi/Salafi organisations, particularly so when it comes to disgruntled, unemployed, isolated youth.
As you can see, the issue is multli-faceted, It is pretty absurd to imply that immigration itself is the issue, it shows that you have an exceedingly superficial understanding of why home grown terrorism occurs.
