Rivals? How did you jump to that conclusion. And i would like to make a point here its france who is hostile towards muslim world.
Eg -
Nicolas Sarkozy: burqa not welcome in France - Telegraph
Link for that second point of your's.
They dont trust, Hell yeah. Who does in this world?
Everyone is up for their own interest and same goes with European continent.
Please don't be paranoid. French national law demands that no religious symbols be displayed publicly, meaning that A Christian cannot display his religious symbol, nor can a Hindu, nor a Muslim and so forth. This is a good law as it makes people feel united and dedicated to one cause while keeping religion out of the way. France doesn't force down shutting Churches or Mosques and this is where freedom is crushed. Not when a stable, secular law is made
Muslims around the world needlessly feel that this is a way of denigrating their religion but they must also realize and respect the fact that they are not in Arabia or an Islamic country to do as they please. Respecting the national law is important especially in a country that doesn't discriminate on religion's basis. When French Christians, Jews, Hindus, Sikhs etc follow the laws, why are they rebelling against the national law? Not wearing a veil doesn't mean that a woman is nude. A full body covering simple cloth is also modest.
Even I as a devout Hindu have been pointed on a trip to France not to display any religious symbol publicly and I respect that because it is the national law. Disobedience of it is disrespecting the host country and encouraging lawlessness.
United Kingdom's weak stand to not setting similar secularization laws has resulted in radicalization of immigrant population, causing terror plots all over your country now almost on a monthly basis. National law is to be followed by everyone
regardless of religion and those who are not comfortable about it, shouldn't visit or stay in the country they find not compatible with.
I am sure that you won't be allowed to run around praising the name of Christ or wearing an "Om" pendant in Saudi Arabia without facing persecution. Therefore, the law of the land must be obeyed and a country cannot be expected to bend down and discard its values just because a set of migrant population cannot adjust to the local laws.
The migrants are coming to another country, not the other way around and therefore it is their responsibility to adjust as per the national law of that country they plan to migrate to.
