Why?
There are many reasons you should be more politically active. First, it's generally a good thing to do. A functioning democracy relies on educated voters. You need to educate yourself, and you need to be able to teach other people about politics. When a society lets itself become ignorant, that ignorance will be inevitably used by demagogues for political gain. Indeed, my second reason is that, right now, our political system is being undermined. Politicians abide by “alternative facts,” rather than admitting their mistakes. Our president seems more and more unlikely to leave office, even if he loses an election. When democracy is under attack in this manner, you simply can’t afford to be unaware.
