Everyone perceives the world in a different way, perceptions are mainly shaped by the people, experiences and environment we grew up with.
Even our own neighbors can be perceived as weird especially if they are from a different country, culture or religion.
People 500 years from now will have way better knowledge of our society mainly because they will have vast amounts of digital records of our lives, unless there is an extinction level event.
They may not understand some parts of our society, but they will have countless billions of books, photos, and videos of us to study or entertain themselves.
The vast amounts of digital media we are creating today will have a major influence in how the future is shaped.
That's why I personally think parts of the environment/culture/customs/traditions we live in are weird and stupid.
That was the point of my original statement/opinion.
In the future people will think we were weird, primitive, superstitious and our traditions stupid, and they will be correct.
Most people pretend to be like everyone else in public, and are our real selves only in the privacy of our homes.
