You don’t know their quality because you refused to engage with them on principle. You locked yourself into your own safe little bubble and found an excuse to dismiss anything that challenges you. You just have to say it’s “extremist propaganda” and you can stay safe. If you wanna do that go ahead, but to then be smug to others and tell them to educate themselves when you’re unwilling to even listen to the positions of the people you’re arguing against is incredibly dishonest. Who do you even think you’re fooling?
