Ardianto, I find your comments to be very strange and full of assumptions, first I must ask if you live in the UK? Because if you don't then we're really talking about two completely different societies.
I live in Indonesia. Yes, I don't really know about British society except from what I have read.
In the UK you will find filth spread everywhere, nudity, pornography, bad manners, hatred against minorities, all of which are noticeably increasing, you can even go and ask a elderly non muslim here and they will tell you the same and how much worse society has became since their time. Schools become the hotbed for all of this, when I was in PRIMARY school, the worst thing that you would be exposed to was occasional bad language, that was around 10 years ago, now however it's common to see primary school children (12 and below) smoking, drinking cans of Alcohol, and a lot of them are getting pregnant, and it gets worse as they progress, until it culminates at university, where what goes on in Student Halls is just indescribable. Not just that but there are problems with what is being taught in schools, things like homosexuality being completely fine and normal, the increasing rise of sex education (Which is soon going to be forced on children as young as 7 years old in the UK) and evolution, I know of individuals who have left Islam altogether while in the schooling system.
I smoke for the first time at school, in primary school. I got my first porn material in the classroom, in primary school. Then when I entered seconday school which was favorite state school (only smart students who could study there) I got my first drug and marijuana. Not difficult to get drug and marijuana in school. First time I drunk by alcohol was in the school tour, which I drank with my schoolmates. We also shared porn material in the classroom. Yes, bad influence from some students made me turn into a bad boy.
But then I got many help from other students too when I began to realize my fault and decide to stop my bad behavior. Like the advice that I've ever heard, "choose your friends wisely". Bad students influenced me to become a bad boy, the good students from the same school helped me back to become a good boy. Many of bad students finally became better too, due to influence of good students.
Evolution taught in my school too, and become a joke among students. We didn't think we are descendant of ape-like animal, we just regard that Darwin has theory like that, just like other people have their own theories. But there is big difference between school in UK and school in Indonesia. In Indonesia, schools are obligated to teach religion in accordance with the student’s religion (except in religious based school).
The moral decay, especially in the UK, is evident.
Moral decay happen in everywhere, not only in UK.
Also why do you assume that just because a child is learning at home that they are barred from society? That is an absurd thing to say, the child would be going to the Masjid to learn as well and for the prayers, not to mention other clubs and activities, such as Muslim swimming club, and other activities from the sunnah like archery, or horse riding (learning how to drive for modern times) etc.
And of course there is good in the society, but now the balance seems to be tipping strongly, if you want to just let society teach your children, then that's up to you, but if someone wants to safeguard their children and teach them Islam properly then they have that right.
I didn't assume that homeschooling will make children barred from society. I just 'worry' that the reason to choose homeschooling is because the parents want to alienate their children from society. But maybe this is just my assumption which based only from few articles that I’ve read.
First time I knew about homeschooling was through Enid Blyton's books that I read when I was kid. From what I've read homeschooling seem like popular among some people in UK who want to give "exclusive, better education". Frankly, I had good impression on homeschooling. Except if the parents force their children to learn at home with specific reason.
My association in internet with Muslims from UK made me want to know further about them. So I started to active to read articles or watch videos about them. And I found an attitude among few Muslims (just few) which regard that socialization with non-Muslim will make Muslims leave Islam. Frankly, seem like they regard that there is nothing good in non-Muslims society. And they indeed, promote homeschooling to save Muslim children from bad influence of British non-Muslim society. I assumed they want to prevent their children associated with society. (But maybe this is just my assumption).
To be honest, if they had attitude like parents in my place which teach the children that there are good thing and bad thing in society, and children should wise in choose only the good and avoid the bad, I would not have assumption like this. But those Muslims clearly have 100% negative view on British non-Muslim society. And teach negative view toward other people to children is not good, of course.
To be honest too, brother, if you didn't write "the current moral decay of society", I would not assume that you have view like them. I am sorry if I have made a wrong assumption toward you.
