All of your examples are opinions as in not demonstrably fact
Two of my 3 examples are not opinions lol. Ads do keep YouTube free. Piracy is theft. Those are facts. You can justify your blocking or ads or piracy however you want but that is not an argument against these facts.
But we're getting into the weeds since the point is the insanity with which people respond, so frequently, and not the disagreement itself.
