Haha, you're so funny, dripping with irony...

Thailand's rules are a bit odd but fairly clear and straight forward. Just try to get into the USA, UK, Canada, Australia, NZ, Japan, China, Taiwan and live there long term if you're an immigrant.
I do find it a bit odd, though, that marriage doesn't grant one citizenship, as with many other Western countries. But no doubt it was abused at one point, when a guy would pop over and marry the first girl he saw at the bar and then dump her as soon as he got his green papers...
