What about Prince William and Kate Middleton inviting "royal tyrants" to their wedding?

They've invited the royals from Bahrain, Saudi Arabia, Swaziland, Qatar and Kuwait (among others). I know it's because they're royals and they're supposed to invite other royals, but it seems a little hypocritical on William's part. The leaders of these countries have brutalized their own people and tried to stifle democracy. I thought he was all about human rights and having a conscience.
