Are we supposed to believe that we weigh more on some parts of the earth opposed to others?
Actually yes. Where you're closer to the center of the earth the gravity is less. Gravity mapping has been around for quite a while.

The model is highly exaggerated and actually has the most important effects removed. Latitude is responsible for the largest gravitational variation and the effect is greatest at the poles (5 parts in 1000) which this map does not show. The second largest effect is at altitude (~2/1000 over 8Km from mean sea level) which is also not shown. Local geological effects on gravity are <2 parts in 10,000, and that's all that appears here.
The local effect is so small that, depending on how massive a local geological feature is, your weight might actually be more seriously influenced by your location relative to the moon.

"Where you're closer to the center of the earth the gravity is less." Nope. You weigh less as you are further from the center of the Earth. Think: scuba divers, mountain climbers, pilots, astronauts, etc.
