That's One Correct Statement
Accusing someone of basing their stance on personal bias is politicizing an issue. Some people can see that works both ways, some can't. Real bias or simple intellectual disinterest/laziness is exposed by refusal to address detailed technical arguments. Debating the details is what science is about not repeating the same phrases over and over like some mystical incantation.
