A united group is generally brainwashed and WAY too powerful. You need to realize that humans are a sick tribal species who demand unquestioning obedience, or else they'll have fun torturing you. An oligarchy is bad enough. An entire society united against all non-confromants is how you end up with Soviet Russia, North Korea, Communist China, Fascist Italy, and Nazi Germany. As a matter of fact, that's why it's called socialism. And that united society usually institutes its cult leaders as the elites anyway. Like all of those countries.

Furthermore, when everyone else is doing something, it takes away all guilt for most; because most only feel guilty as far as they upset social norms. A united mass will therefore have even less of a conscience than the elites do now.

Fascism in particular arises when a whole society is not only united, but joining forces against a common enemy. The Germans united against the Jews. The communists united against the rich. SJWs united against white Christians. The "new right" is uniting against SJWs and anything they've co-opted. At that stage the ends justify the means, and the society is willing to commit the most morally reprehensible deeds imaginable to destroy the enemy. All non-conformants are automatically considered an enemy and must be eradicated. Hatred for the enemy trumps everything else, even the reason that enemy is an enemy in the first place. It's blind rage and revenge, and they don't even realize they're destroying themselves inside out. Evil nature is at its fullest and the society will needlessly torment those it declares enemies for amusement, without so much as an afterthought. Anyone who doesn't take a side is regarded as the enemy from all coalitions. For example, since I'm not joining the new political bandwagons, I'm regarded as part of "the problem" by everyone. SJWs accuse me of being a far-right white supremacist bigot. And the "new right" considers me a leftist degenerate. Destroying the enemy is all that matters to them, even if they destroy themselves in the process. They don't even remember who they are.

This is not the same as a loosely united force against an oppressor, such as the elites, a tyrannical state, a cabal, or whatnot. Nor is it the same as boycotting. This is when it gets to the point where a certain group of people is so despised that they become the scapegoat for every single problem the world has, and the people are willing to use brutal government action to watch them go down. For instance, the Jews. It stopped being about taking a stand against the elite Jewish cliques who are racist against goyim and super greedy, and became "all Jews are the boogeyman, let's torture them and kill them all and get our revenge!". Now tell me that doesn't sound exactly like: "all white people are racist", "all men are rapists", "Christians are bigots", "black people are all criminals", and "LGBT people are destroying society". It isn't about political oppression anymore; it's all about social categories one party or another dislikes. And those who used to fight for freedom are now embracing tyranny to wipe them out. With not even a thought about the consequences.

I cannot stress this enough: Humans cannot be trusted!
