Okay, lets see if I can make you laugh some more
Firstly, the insistence that "artists can paint anywhere and get insperation from tutors online" is, at best laughable, at worst, complete ignorance of the skills needed for art. Considering that in order to do most art degrees an art foundation course is required as well as A-Levels, it seems unlikely that art is simply something you can do, or you can't. Obviously, a certain amount of talent is needed, but on top of that grounding in the basic skills needed for art is necessary. This indicates something which must be taught, yes? Raw talent is not enough alone. And without artists, who will draw up the designs for the equipment needed in your experiments?
You say that at university, scientists finally get labs. Well, at university, artists finally get access to all the equipment they would ever need. So what's your point?
That particular sentence I quoted, "artists can paint anywhere and get insperation from tutors online", contains another example of exactly where you're wrong. The word is spelt 'inspiration'. Perhaps if you had learnt A-Level English Language, you would be aware of that. The study of language is necessary to communicate efficiently and effectively. In fact, decent communication skills are at the core of the sciences you hold in such high regard. Tell me, how do you plan on sharing your scientific advances if you cannot communicate them?
Following on from this, we come to modern foreign languages. How do you plan on sharing your scientific discoveries with the international community if there are no people around who can speak the languages of other nations?
Ethics are another important part of society, and are learnt in subjects such as RS, psychology and law (as far as I'm aware). Who will decide whether it is right to use the weaponry science creates, if there is no-one with a sound knowledge of ethics? And without a knowledge of history, how can we learn from the mistakes of the past and know when not to use them?
Obviously, science is very important. But without arts and humanities, it would be nowhere. They are reliant on each other, and are of equal importance.
I don't even study humanities, my A-Levels were chemistry, biology and psychology, and next year I'll be a computer science student. But in my opinion, it is important for people to recognise the importance of both arts and sciences, regardless of which you decide to study further (if indeed, you study further at all).
Unfortunately however, you only seem to be able to one side of the argument, and that is perhaps why some people believe that there should be compulsory arts and sciences right up until 18.
I'm sorry for the long post, but I absolutely cannot stand ignorance.
