I'm really stuck by how easy the interment makes confirming one's biases and feelings.
In the old days you would have to put some effort into it.
Bear with me for a second....
Remember "chainmail"? Did you ever get any or personally know someone who got some?
No wait, that is adjacent to where I wanna go...
Remember "midnight movies" or "off-off-Broadway" theatre productions or "new" music or certain festivals, you know, stuff that might better be described as "things you pay for that were very much non-standard and likely get you considered some type of deviant".
It was something that you had to work to find and there was a cost to it. But oh, once there, how great was it to find what you were looking for, how fantastic was it to be surrounded by you fellow ilk?
Suddenly what was out there was normal, accepted.
But really, that was all in your head.
To the rest of us, your kind were a pox on the great collective.
But rather than stamp you into grape jelly and export you to feed the starving in Estonia, society said, "Hey, we can make a buck off of this and say, 'freedom of choice' and give them a safe place to do their thing in ornate buildings with geometric signs nailed to walls, warehouses, or the desert hinterlands."
Eventually equilibrium was achieved and was constantly be challenged, but hey, you could go to your Striper show on Saturday night, skip Sunday morning church due to the hangover, and Monday, back to designing weapon systems while thinking about your affair with your spouse's best friend's dog trainer.
Then came the internet and greatly lowered the barriers of entry to (your version of) weirdness. In a way, it was improved, targeted chainmail for everyone all the time, and boy was it cheap for both producers and consumers.
Dilettantes, that's the real problem.
