I've always suspected that the " end of the world" will be as a result of collective nervous breakdown rather than fiery apocalypse, and some of the posts here are rather proving the point.
Whipping up hatred against any group of people can lead to them becoming fearful and defensive, tensions rise, and oh look, a self-fulfilling prophecy.
To the posters claiming that there are no parallels with other periods in history when fascism has become popular, the first steps towards it are rising nationalism, and encouragement towards violent / oppressive rhetoric towards the "enemy" of choice.
We're seeing it and hearing it towards immigrants, the disabled, the poor in general especially benefit claimants, women, basically anyone who, regardless of actual character or circumstance falls under a sweeping generalisation that can be leveraged as "it's not fair" that we currently live in a society where the vulnerable and disadvantaged are afforded humane treatment. And that humane treatment is realistically the bare minimum and extremely conditional.
One of the strong undertones at the moment is "stop them breeding" alongside dressed up versions of euthanasia. That is also a fascistic attitude, the cleansing of undesirables.
If a leader or party comes into power that panders to the rhetoric and puts policies in place that reflect the alleged will of the people, there tends to be mission creep, and the turkeys who voted for Christmas will be very bewildered and indignant when they suddenly find themselves "undesirable".
Everyone is being played for mugs here by rich and powerful people punch drunk on the fact who give not one shiny shit about the pawns on the chessboard. They're hoping we'll do the hard and messy bit of turning on each other - there'll likely be casualties on the way, and whoevers left will find themselves wondering what a human right was and how people used to make their feelings felt before political dissent was criminalised. And that will be so much easier to do thanks to technology and pre crime detecting AI. (Announced by our government earlier this year, and rolling out in the US next week).
