You've been looking in the wrong direction, the dangers are coming from the right.

The world, and the societies within it, continually and progressively moved to make it a better place for as many people as possible. Slaves and fighters usd to kill each other for the entertainment of the wealthy, that was recognized as being barbaric and unfair and so the practice faded out. People used to be killed as a form of sacrafice, again that practiced was stopped as the communities recognized it for what it was. People were owned by other people and used to complete manual labor, that practice was faded out. People were punished for practicing their preferred religion, that practice was faded out. People were prevented from voting because of their gender, race, wealth, social standing, that practice was faded out. People were forced to work excessive hours every day, that practice was faded out. People were punished for having sex with people of the same gender as them, that practice has been largely faded out, but still continues in part of the world. People were prevented from sharing public spaces with others because of their race, that practice was faded out. People were prevented from gaining education or employment in particular areas because of their gender, that practice was faded out. People were prevented from running the marathon or drinking in certain areas of bars or playing on certain golf courses, because of their gender, that practice was faded out. People were prevented from forming unions to advocate for better work place conditions, that practice is in the process of being faded out.

This wasn't a linear progression, there were steps forward, and then some backwards, some societies moved forward faster than others, etc. Some practices that were common in the past but no longer are permitted in some areas now, still exist in some parts of the world as change is yet to get to that area. But the motivation to fade out every single one of these practices, in the past and in to the future, is what would be described by the modern day Right as being 'Left Wing', 'Progressive' and 'Woke'.

It is demonstrably false to suggest that Left Wing Ideals are something that have only appeared since the late 20th century, or early 21st century as you and some people are intent in claiming.
