It’s an interesting study and I understand why people would feel that way, the only thing that rubs me the wrong way about these things is the human tendency to paint someone in a totally negative light once they see the “red flag.” I feel the comments are evidence to that fact. If you know someone who hold offensive opinions you should actually ask them why they hold that opinion. People are enormously complex and their personalities or even morals cannot be boiled down to a small handful of extremely polarizing opinions.
