I always think that the difference between a conservative and a liberal is often the lack of nuance in a conservative’s views. This can often come across as ‘winning’ in a discussion, because from a liberal perspective, there are few universal truths so a blanket statement can lead you to being “caught out” and in my experience, you’re rarely listened to in order to explain the nuance.
I do know some liberals with viewpoints that lack nuance, however, and critical thinking.
