Cheers @anglotrucker for your suggestion! every human being is unique - I lived in a foreign country a great part of my life. I encontered few people tagging me XYZ, but others that received me extremely well. It is in human nature atributing values to things, people, etc. It is really hard, but I try myself to look beyong all this - not focusing on the things that make us different but on the ones that make us equal.
Of course we have to have values that partially comes from cultures that exist many years before we were born - funny part is that we look our society as some static structure - however, everything changes even people change. Would like to quote an article from BBC:
Quote
In Victorian times, society was strictly layered - not only into rich and poor, or even upper, middle and lower class, but hundreds of 'grades'. People were expected to 'know their place', and the Church taught them to be content in their 'station'. Dickens did not like the effects of social class.

Just wanted to list this to put in perspective which were the values in the past (from historical perspective almost contemporary) and which are the values and flags we have today.

If we consider this, it might make us understand life and culture as a flow, and in that sense mutable.

In 100 years (hopefully sooner) few students will have to listen to the "AI professor" during 30 minutes just to understand what the word "feminism" meant many decades ago.
