Being a person who has very clearly defined views on religion and politics, part of what I like about this issue is that it has nothing to do with religion or politics.
You may not like my fundamentalist Christian beliefs. That is fine. Just make sure you visit the links. You may think my morality stinks. You may despise my Conservative politics. You may be, horror of horrors, a member of the Labour party. But if you always remove your shoes at the door, at least we have something in common.
Removing shoes in homes unites people.
Fundamentalist Muslims in Indonesia remove their shoes at the door. So do humanist liberals in Sweden. Hindus in India remove their shoes. So do Christians in South Korea or former Communists in Russia.
It may be that you are an environmentalist. You may remove your shoes because you worry about pollution and toxins. Or you may be an Ecosceptic like me. Nevermind. I can be Green on this issue. Unless being green means only buying a pair of slippers every five years and not twice a year.
You may like to wear slippers in your house, you may prefer to go barefoot. Or perhaps you always wear brightly coloured socks on your carpet.
You may provide slippers for your guests, or you may expect them to bring their own.
You may visit because you just think that stocking feet are kinky. Never mind, you are welcome to visit anyway.
