It's often said that you shouldn't talk about politics, religion or money. I tend to think those are all part of the same thing: conversations about how the world is, and should be, organized. Anyone who's been watching the American electoral system warm up its engines will be in no doubt that your views and status in any one of those prongs affect the other two. And all are inseparable from the cognitive biases that your context in the world has given you.

So let's restate the maxim: it's rude to talk about the world.

Why?

The reason that's most often given is that people might disagree with you. It might start an argument, someone might be offended by your viewpoint, or you might be offended by a deeply-held position from someone else. As the thinking goes, we should try to avoid offending other people, and we shouldn't be starting arguments.

Living in a democracy, I take a different view. Each of us has a different context and different opinions, which we use to inform the votes we cast to elect the government we want, allowing us to help dictate how our communities should be organized. That's awesome, and a freedom we shouldn't take for granted. It's also the fundamental bedrock of being a democratic citizen.

I want to be better informed, so I can cast better votes and be a better citizen. Which means I want to hear different views, that potentially challenge my own. If you define offence as a kind of shock at someone else's disregard for your own principles, I want to be offended. I want to know other peoples' deeply-held beliefs and principles, because they allow me to calibrate mine. I don't exist in a vacuum.

I think the world would be better if we used our freedoms and were more open with our beliefs. The challenge is that it is not always safe to do so. Middle class politeness is one thing; for millions of Muslims in America, like communists and Jews before them, sharing their beliefs can be life-threatening. For a supposedly democratic nation, America is spectacularly good at stigmatizing entire groups of people.

I'd like to think that this is where the politeness principle comes from, as a kind of protection mechanism for more vulnerable members of our community. I don't think that's the case. I think it's much more to do with maintaining a cultural hegemony, and the harmful illusion that all citizens are united in their beliefs and principles.

Citizens don't all have the same beliefs and principles. This is part of the definition of democracy, and we should embrace it.

Citizens don't all have the same privileges and contexts. As a white, middle-class male, I have privileges that many people in this country are not afforded, and a very secure filter bubble to sit inside. I think it's my duty to listen and amplify beyond the walls of that bubble. Candidates for the President of the United States are, in 2015, suggesting that we have "a Muslim problem" in terms that echo the Jewish Question from before the Second World War. Even if you don't believe in advocating for people in ways that don't directly affect you, this directly affects you. It's all about what kind of country we want to be living in. It's all about how it's organized.

It's also about what kind of world we want to be living in. I think it's also my duty, as a citizen of one of the wealthiest nations on earth, to listen and amplify beyond our border walls. Citizens of countries like Iran, Yemen and Burkina Faso are people too, with their own personal politics, religions, hopes and dreams.

We've been given this incredible freedom to talk and advocate, to assemble and discuss, and we should use it.

Yes, there will be arguments. It would be nice to say, "hey, we shouldn't get angry with each other," but these are issues that cut to the core of society. Tone policing these debates is in itself oppressive and undemocratic. And while I'd like to be able to say, "we should have a free and even exchange of ideas, and I won't think less of you for what you believe," that actually isn't true. If you believe that Muslims are second class citizens, or that the Black Lives Matter movement isn't important, I do think a little worse of you, just as some of you will likely think worse of me for thinking socialism is an okay idea or for not believing in God. We can respect each other as citizens, and have respect for our right to have opinions. We should still talk. And as dearly held as my beliefs are, I want to know when you think I'm wrong: it's how I learn.

What we shouldn't do is tell people that they should just accept what they're given, and take the world as it is. That's not what being in a democracy is all about, and it's what we do when we tell people to shut up about what they believe.
