Some of them are. According to wikipedia, it originated as a communist movement but later became a different name for "classic liberal" because American left-wingers "stole" the term "liberal".
I guess you could argue that classic liberal cannot be conservative because they don't want to conserve the status quo, they want to go back to some earlier state. But when you present some regulation in front of them, they take the conservative stance - being against it.
On a different note OP hit itself in its confusion, there are definitely libertarian Linux users. Look at Mental Oulaw (anarchist) and Luke Smith. edit: or go to some Odysee comment section. Apart from the crash test dummies who hate Mozilla because "the trannies!!!!! >:(", you will find libertarians.
I cannot give you any source, unless you want to waste hours of your time watching some car videos. The difference between an n-word pass and rice-pass is what you mean with that. Some secret way of saying the n-word does not change its racist connotation but a ricer by default has nothing to do with race. If you want to be racist, you would have to explicitly specify that you are talking about the owner's race or the car's origin or whatever.
That's not normal human behavior. Try to imagine it. 3 people are going down the street. One of them points out that a car on the street is "riced". Second one tells the third who is of Japanese origin, that he should get offended because of the word's origin. It would be weird to get offended because someone told you to.
