As you can see from the below definition, critical thinking is not required when employing reason and/or logic
Reason (logic)
And c and d support the need for usings reasoning and logic to determine facts and not subjective thinking.
c. A fact or cause that explains why something exists or has occurred: The reason for the building's collapse is unknown.
d. Logic A premise, usually the minor premise, of an argument.
Here is support that critical thinking uses reasoning and logic

True! Which is why I think your definition that requires the person to be sentient in order to be considered a person; a poor requirement.
Thats only if you think the mentally ill or people on life support don't have any consciousness. However that is your definition I ain’t arguing with cha, just pointing out not everybody is gonna agree with you. [/quote] Its not my definition. ITs the official and widely accepted definition.
Not subjectively based on their personal opinion? Then why does these basis differ from person to person?
I think I have been through this with you before. Just because people differ on their views about something objective doesn't mean there is not objective truth. It may be people are biased, have self interest, have beliefs and these influence the way people see things. So we cannot rely on subjective thinking to determine the facts/truth.
In recent years we have been able to understand more about the Fetus. We now know for example that the Fetus can feel pain. So as we understand the facts better we can then determine whether abortion is destroying human life or not. But we can only do that if there is an objective measure of things ie the Fetus is proven to be life objectively and we know that taking a life is morlaly wrong.
As I said before; those in power make the rules. In the case of slavery, those who were against slavery became more powerful than those who were for it. (not to mention the fact that the Industrial Revolution and technology of that time began to make slavery obsolete)
But under a subjective moral system those outside power trying to change things should not have to protest and push slavery supporters out of the way because having an opposing view is not wrong.
THose protesting defeating pro slavery supporters only makes sense if morality was objective because morals cannot improve under subjective morality they are just different opinions and preferences.
