Marinating.............................

"It took me years of writing on the Internet to learn what is nearly an iron law of commentary: The better your message makes you feel about yourself, the less likely it is that you are convincing anyone else. The messages that make you feel great about yourself (and of course, your like-minded friends) are the ones that suggest you’re a moral giant striding boldly across the landscape, wielding your inescapable ethical logic.  The messages that work are the ones that try to understand what the other side is thinking, on the assumption that they are no better or worse than you. So if you are actually trying to help the Syrian refugees, rather than marinate in your own sensation of overwhelming virtue, you should avoid these tactics." 
-Megan McArdle, as excerpted from this post on "refugee policy"
