Even if you hear or read something about a certain culture, it’s important to realise that doesn’t mean everyone from that particular background acts/thinks/believes the same thing. Just as not everyone you know has identical beliefs; people who come from different cultural backgrounds aren’t all a certain way either.
One of the biggest difficulties to overcome in understanding cultural differences is making judgements based on one opinion. Do your own research and make an effort to actually learn about people instead of making broad brush statements.
The main thing to remember is that everyone, no matter what their cultural background, has different opinions, habits and ways of life. The quicker we accept that everyone is different, the easier it becomes to understand and embrace cultural differences.
