The solution to this issue is not some Holy War against Islam as a whole, and nor is it the abrogation of the civil rights of Muslims in the west whether they are natives or immigrants.
The most important are human rights and freedoms.
Of course, in real life, in mixed environment where non-Muslims and Muslims live, tensions exist always, it depends among other things, from the number of Muslims in any area.
And non-Muslims cannot escape the provisions of Muslim rules and Sharia law.
I will give here one example, it refers to the rules of marriage.
Muslim woman is forbidden to marry a non-Muslim man.
In mixed environment certainly there are situations where non-Muslim man and Muslim woman fall in love which each other (although generally Muslim families strictly kept young girls).
But it is not allowed and non-Muslim man can have difficult destiny.
...
There is only one way to resolve the situation with a happy ending.
And whole society (in that area) can relax because it avoided explosive situation.
Only solution is that non-Muslim man convert to Islam, and his children will be true Muslims.
Yes it is only solution, but this small example shows how
non-Muslims take dhimmi position, and obey the Islamic rule and Sharia law.
It is necessary to understand Muslim supremacy in Islam.
Also, restrictions exist and for men.
Muslim man can marry Christian, Jewish or Sabian woman, but it is not allowed to marry atheist woman, zoroastrian, hindu, buddhist woman etc. In practice there is connivance, for men there are no such strictness as for women.

Ruling on a Muslim man marrying a non-Muslim woman and vice versa (Muslim website)
It is not permissible for a Muslim woman to marry a non-Muslim from any other religion, whether from among the Jews or Christians, or any other kaafir religion. It is not permissible for her to marry a Jew, a Christian, a Magian, a communist, an idol-worshipper, etc.
The evidence for that is the verse in which Allaah says (interpretation of the meaning):
“And give not (your daughters) in marriage to Al‑Mushrikoon till they believe (in Allaah Alone) and verily, a believing slave is better than a (free) Mushrik (idolater), even though he pleases you. Those (Al-Mushrikoon) invite you to the Fire, but Allaah invites (you) to Paradise and forgiveness by His Leave, and makes His Ayaat (proofs, evidences, verses, lessons, signs, revelations, etc.) clear to mankind that they may remember”
[al-Baqarah 2:221]
Imam al-Tabari said:
What is said concerning the interpretation of the words “
And give not (your daughters) in marriage to Al‑Mushrikoon till they believe (in Allaah Alone) and verily, a believing slave is better than a (free) Mushrik (idolater), even though he pleases you” is that what Allaah meant by that is that Allaah has forbidden the believing women to give birth to a mushrik, no matter what kind of shirk he believes in. So, O believers, do not give your daughters in marriage to them, for that is forbidden to you. For you to give them in marriage to a believing slave who believes in Allaah and His Messenger and that which he brought from Allaah is better for you than to give them in marriage to a free mushrik even if he is of noble descent and honourable origins, even if you like his descent and background…
But it is not permissible for a Muslim man to marry a Magian (Zoroastrian) woman or a communist woman or an idol-worshipping woman, etc.
The evidence for that is the verse in which Allaah says (interpretation of the meaning):
“And do not marry Al-Mushrikaat (idolatresses) till they believe (worship Allaah Alone). And indeed a slave woman who believes is better than a (free) Mushrikah (idolatress), even though she pleases you”
[al-Baqarah 2:221]
) I know quite a few Italian women who have married Jewish men, particularly professional women. They joke that they should form an organization.
