> it's called dark matter because it only interacts gravitationally, not because we can't explain why it should be there.
No, the notion that it only interacts gravitationally came much later. Previously it was assumed that it might simply be... dark matter, regular old gas, dust, rocks, stellar remnants, black holes, etc. that were not luminous. Take a look at MACHOs and WIMPs for theories about "dark matter" being regular standard model stuff that simply wasn't glowing.
It wasn't until decades later that "it only interacts gravitationally" became the dominating notion, entirely based on the preponderance of observations indicating something like that.

Okay, I concede you that. It started out as "matter we can't see," and today a popular interpretation of that is that it doesn't interact with light at all. My mistake.
But, that also wasn't really my point.

Your point was some crude dismissal of dark matter based on what seems to be a gross misunderstanding you have. Sorry for correcting your misunderstanding. It must hurt your feelings, being corrected.

at no point have i dismissed dark matter, i have only presented arguments against the evangelization of dark matter, which this article supports. you argued beside the point, and have now volunteered yourself to exit the conversation.
rest easy, your words are as sharp as you are

"the bit where he says that no evidence doesn't mean it doesn't exist is frankly embarrassing" was pretty damn dismissive dude, GTFO with that dishonest-ass nonsense lol :D

if you interpreted that as an outright dismissal that dark matter is correct, then again, you have entirely missed the point... Saying that "not having evidence doesn't mean it doesn't exist" is not a strong argument for dark matter, or a strong argument against alternatives. It's pleading, and doesn't really imply anything meaningful. I hear it when people ask for proof that god exists.
I don't understand why you insist that I have claimed dark matter is incorrect, maybe I am failing to communicate my point properly, but that definitely is not it at all. I would appreciate it if you took some of your valuable time to respond to literally anything else that I have actually said, thanks
