Capacitors can leak, dielectrics can conduct, it has a I-V curve at DC, so it could be resistive. Your pure, ideal capacitor in your head does not leak, but I look at all the capacitors in my parts storage, and all of them has a leakage current (I) when high enough voltage is applied to it (V). Should I relable it as all resistors?
Resistance, capacitance, inductance are the words you are looking for. Those are the the theoretical physical properties that are well defined. Resistor, capacitor and inductors are the devices that does mostly what it says in the name, but we all know it isn't perfect. When I put a capacitor symbol in my schematics, I don't mean to spec in two magically floating metal plates separated by a perfect vacuum, I am placing a tube containing a couple strips of foil separated by paper soaked in electrolyte, a.k.a. an electrolytic capacitor on a PCB.
You can say a diode has resistance, which I am sure you can wrangle your math to proudly show it is so, fine, but that does not mean "an LED is a resistor". The ability to use maths and quote books to make pointless arguments proves you have linguistic intelligence, but it does mean not you are an intelligent person.
If you walk up to a straight dude, say he is gay, get punched in the face. You can argue "dude you are dumb, I saw you laughing, and according to the dictionary gay could mean happy, so I was correct. Did you even study English?". Who's the dumb one in this story?
