That's not true. Just because they're immaterial doesn't mean they don't exist -- best practices in terms of social interaction aren't limited to humans, and most of what makes life what it is -- our thoughts, dreams, imaginations, even our religions -- are immaterial and unfalsifiable. Other species even have self-awareness and theory of mind, so you can't argue rights don't exist.
Your reasoning is a blatant bandwagon fallacy and therefore invalid. If everyone else in the world decided blue-eyed people didn't have rights, those blue-eyed people would still have them. You all simply decided to violate them collectively, and the revenge and war your actions would bear would be ones you rightfully deserve. Rights aren't about who can do what. They're about your existence on this earth and what it is you should prioritize and choose to fight. They are the spiritual essence of self-worth.
They exist regardless of whether other people agree to them or not. That's the whole point of rights.
You're clearly looking for a way to either dismiss rights or dismiss me, so let's make it easier for you: That's just lame ass authoritarian tripe you were told to convince you to submit to the lockdowns and other covid restrictions. You're one of those types. The type who watched everyone collectively ignore and reject respect for human rights and decided, "Well, if rights truly existed, how could we have gotten away with bullying everyone else to being put on house arrest for three years and all the other cruel shit we did to them?". And you're just an idiot blowhard for thinking that way.
Now prove my point by completely derailing the debate with meaningless pro-lockdown talking points, come on. 🙄
