This seems rude to me too. Friends I have who typically take their shoes off when they come inside their homes have always insisted we don't have to. If I think about it, I do, but half the time I don't think about it because we didn't grow up doing it and haven't done it throughout our married life.
If someone asks me to I will, but i would never ask another to do that. they might get dog hairs on their socks from my tile floors!!
