I'm absolutely astonished that you would come out with such a ridiculous, anachronistic idea. Tell me, what precisely happened in your life that gave you the idea that I owe anyone any kind of duty simply because I was born? Did you watch a Disney movie?
Clearly in your mind there is a logical chain from some starting point to the end point of voting being a duty. I challenge you to write this down in words. To express your idea lucidly and rationally. Convince me. I dare you to try. Do you have it in you? Or can you only embarrass yourself further?
Because you have the chance to change things for the better
How?
and if you don't take that chance but still keep complaining about things then all you are doing is pretending you care
Complaining doesn't imply caring. If my neighbours keep me up until 2am having parties on school nights and I complain about that, the complaining doesn't mean I care about anything beyond my own wellbeing.
LOL
