Ok being Australian does explain a lot. I appreciate your candor and conversation thus far. I am not sure how people are politically in Australia so forgive my ignorance but in America both the Democratic and Republican party wear their party as a badge and often a staple of their personality. Unfortunately it has become a " You’re with us or You’re against us" mentality which helps no one when it comes to talking about issues. Right wing supporters here will go to the grave believing or too stubborn to recognize these people are indeed crooked. Just as the Left will support Hunter Biden even though he is fairly scummy too.
In short, the political bias in America is strong and people dont like to change their mind or admit they are wrong.
