That a political movement can rise like this by the conscienceless and moral-free exploiting people's trust, good will and basic good intentions, and that many and multiple agendas are being met inside the whole. And by people being useful idiots who fall easily to marketing and patter, and don't engage their brains.
That quite a lot of humans apparently really like a bit of religious zealotry and aren't that bothered what the religion happens to be if it lets them do the behaviours involved.
That as a society we are in a mess of sentimentalism, individualism, fantastic entitlement and selfishness, a belief that very wobbly boundaries are okay, I suppose, I dunno, (unless someone says no in a way that would require self denial, boundaries galore on that) and a lot of very bored young people with too much time on their hands, no sense of belonging or self, lacking for a healthy sense of community, in a time in history when the most effective way to get attention and celebration is to be very unhealthy and dependent, and not enough reality so that they are hooked on high emotional input and drama, whether being those in crisis or the rescuers of those in crisis. And I'm not sure how we come out of that.
And that the left are completely fucked, they are batshit insane and with a lot of beliefs that historically lead to absolute disasters, and they're all either too thick to see it or don't care as the gravy train currently works for them and it won't be them who suffer when it all falls apart, which as a naturally centre left voter is really bloody depressing.
Oh and that women were really bloody kidding themselves that they'd achieved anything much since suffrage.
It's been a grim few years.
