"there’s already a bias" - so you're saying that you can't ask fascists what they have for breakfast, because somehow being a fascist means they have different breakfast preferences to everyone else? 😂
"Maybe that bias isn’t important" - you're finally catching on
"you have to prove it" - no I don't. YOU'RE the one claiming it's biased, YOU are the one who has to prove that claim 🙄
"you have to prove it’s a random sample" - nope, you have to show it was biased
