Yes, but their opinions aren't equal if only one has applied critical thought successfully. There is no wiggle room for improvisation or rogue "logic" in these matters. Recall the addition example. If I see 2+2 and conclude 4, and somebody else says that he sees the same two digits but concludes 5, they can both be wrong, but they can't both be right, and we have an empirical test to decide which if either is correct. We can combine two apples with two more and count them when combined.
“Water is two parts hydrogen and one part oxygen. What if someone says, "Well, that's not how I choose to think about water."? All we can do is appeal to scientific values. And if he doesn't share those values, the conversation is over. If someone doesn't value evidence, what evidence are you going to provide to prove that they should value it? If someone doesn't value logic, what logical argument could you provide to show the importance of logic?” - Sam Harris
