It is more true online, and for a lot of reasons.<p>I meet someone at a party and we become Facebook friends. I then post some sort of political article or comment to my feed. They see it, disagree with it, and (likely) either comment on it in a non-polite manner, or stay silent, but either way categorize me in their head as a crazy right&#x2F;left winger. Why? Because these are what is easiest to do for &#x27;crazy&#x27; opinions coming from strangers.<p>Compare that with what can happen in real life. I get to know someone over the course of multiple interactions; all my political comments are kept to those I already know and trust. Eventually we get to a point we know and trust each other, and I venture an opinion, one they disagree with. They say &quot;I disagree with that&quot;, and we discuss it. Why? Because we already know each other, value each other, trust each other, and are seeking legitimately to understand and&#x2F;or sway one another, while also preserving the relationship.<p>The internet has essentially made it so the thoughts we used to reserve for those we knew in depth, are becoming aired to strangers, and responded to accordingly.<p>While it means that insular bubbles of thought (the rural family who doesn&#x27;t know anyone who believes in gun control, say) are encountering people who disagree with them, those people are strangers, and there&#x27;s no reason to give them any credence. If anything, it just makes one even more vociferous, because now you can preach to people who -aren&#x27;t- in the choir.
