Why are so many young Muslims still so religous?

I suppose Muslims are ethnic minorities in britain so their parents are more likely to emphasise their cultural/religious difference so their children are proud of their heritage, also modern-day Islam has a lot more rituals than modern day Christianity so to ‘be’ a Muslim you have to actually be involved in them whereas a lot of Christians barely even go to church. But I’m no expert so don’t quote me on it

Well muslims aren't an ethnic minority. Anyone of any skin colour can be a Muslim. Jews are an ethnic group (well actually several) but descend from a a single group, but not all Muslims are "Arabs".

If you look at white, traditionally Christian British people, raised as Christians, they have adopted a secular lifestyle and don't follow the Bible to every single letter (if at all if they completely reject it). Yet it seems people raised in Muslim families still seem to remain religous, yet everywhere else religion is declining? Any incite.

religions are an operating system for human beings and human societies. islam is just running quite well atm in the human brain without much threat from other religions like the dying xtianity and the dead judaism. why wouldn't its followers be devout when it's the only religion with substantial power and influence?

Christianity has substantial power and influence though, just look at the way it influences politics

politics is about power. Christianity doesn't effect it. talk to the average joe and they will vomit if you mention Jesus. it has no appeal to people or the powerful. however there are christian interpretations like modernity is all a worship of Moloch or something, that's what i believe. i can joke about eating fetuses and people laugh.

the truth is the truth.

the truth is the truth.

Its a testament to Islam's Truth compared to other so-called religions.

It's more of a testament to cultural pressure and the power of indoctrination as evidenced by the fact that virtually all religious people find the "truth" in the religion of their parents (including you two by a measure of great certainty).

Christians might equally say "the truth is the truth" over the fact that they are the largest religious group in the world. Their claim would have as much validity as yours (which is none).

I would say many young people are religious Muslims because they have learnt the meaning of their religion whilst they were at a young age. Not all Muslim teens are religious yet they do have that knowledge of their deen and also families tend to talk more about religion and what it means to us. So young people begin to be able to understand religion and therefore act up on it. I mean, I'm a Muslim and I'm not perfect but I know what my religion does and does not allow.
Also, whilst people of other religions may be lenient with their religion, Muslims when they begin to have that connection with their religion, it's not something that they tend to let go. To religious Muslims their religion becomes a very Important part of who they are.
Like in Christianity you have the new Testament and the old Testament whereas in Islam the Quran has not changed.
It's like, Islam has been built on a solid foundation, it has its rules and everything made explicit since day one. And there has been no changes to it ever since.
