Wait, if you're a Republican and you're admitting that Republican politicians don't have critical thinking ability, then why are you still voting for having them run a country and affecting the livelihoods of millions (billions) of people?
If the only Republican policies you're supporting are benign ones (as a non-American, I don't know which those are), are they worth all the ones that oppress and take away the rights of others?
And if you're a Republican but not a fan or voter of the Republican party as it stands, then maybe you need to reconsider what your definition of a Republican is, because Republicans themselves today are defining themselves in ever-bolder terms.
