I'm quite an odd one, really. My absolute ideal would actually be rather left-wing, a land where everyone is equal, education is free and there is no poverty because everyone enjoys a high standard of living. Here, the state would act as a benevolent leader, providing direction to the nation and preserving order to ensure that all benefit from the profits of our success.
As I'm sure you agree, that sounds very fluffy and is very idealistic. I find myself realistically therefore in the centre-right of the political spectrum. I recognise that everybody is not equal (and I don't mean shouldn't be entitled to equal rights, I mean equal in very general terms such as intelligence, work ethic etc) so therefore this idealistic state cannot exist. In reality, those in positions of power cannot be fully trusted to be benevolent to all of our citizens, although the current system of democracy does a pretty good job of ensuring that each government acts in the broad interests of the people, regardless of which party wins. As people are not equal, it is therefore just that there are differing levels of wealth, although I think the government should have the responsibility of limiting the power of those who aren't elected. Education can't be free without excessive taxes or else universities will fail to run, and taxes themselves should be kept at a minimum so as not to punish the individual by taking a part of their salary. It is perfectly fair to pay for your own education, but the loan system is effective at making sure people can afford it who do not have the money up-front. In some ways I'm also a bit isolationist, in that I want less interaction with certain parts of the world but more with Europe/Anglosphere countries (and China/Japan, I guess). I also think Islam has the potential to cause significant damage to Western culture and freedoms. By and large, most Muslims who grow up here are very agreeable people and are similarly likely to hold conservative stances on issues such as homosexuality as many conservative Christians are, so as long as they don't act on those beliefs and try to integrate with British life then that's fine. It's the ones who immigrate directly from the Middle East that we really ought to be worried about, as they have come from a society that in many ways is the polar opposite to our own.
So I describe myself as a Conservative because they're the only realist party, and the only party prepared to take a stand against mass culture change. I differ from many on this site whom I usually agree with by my promotion of the EU as a good thing, although I admit it is no way perfect in its current form. Maybe the idealist inside me wants to believe it can change, idk. But I find that human nature drives me towards realism, which a great many students refuse to acknowledge as a fact of life.
