Do you really think you can change minds that are petrified with partisan views? Whether it be politics or religion or anything? Have you changed anyone's mind about anything ever? Has anyone changed YOUR mind about anything ever?
There is benefit to hearing what people think. That way you can figure out why they say what they say. Are they "objective" in their views and independent or do they all sound alike because they are always reading from the same approved script and dare not deviate a word from it?
It's just an exercise of the mind. Engaging in lively conversation is a good thing generally. It energizes and keeps the old brain working. But if your goal is to convince someone that your view is correct and all other views aren't fuggedddabboutitt!
