This is an interesting read on a topic that is relevant in a variety of contexts.

So who tries to establish as a "right" something that has long been a "reality" among people everywhere, tries to fill a full bucket with water by claiming that there is a right to substitute water for water

I think this is the crux of the matter- what, who, how, and why?

There's no single answer. Some have an explicit agenda, some are just following the trend without thinking of the consequences or afraid to lose livelihood, and others just follow their base mammalian territorial instincts (to make you bend to their demarcated will and do so explicitly such as by waving the team colours and symbols, raising hand in non-standard salutes, or murmuring the same nonsensical phrases over and over).

These are all controversial topics and personally I'm way beyond discussion at this point, but I'm glad that you brought it up because we do need to have the courage to speak up before there's nobody left to speak for us.
