This date is of great importance for Mexicans and I'm super proud of being one but, hate to be that guy, there is nothing to celebrate. Corruption, massacres, drug war, the dollar is almost $20, journalist are being censored or killed and there seems to be no light at the end of the tunnel. To celebrate today is to approve of all the things listed above and accept Peña's legitimize.
Fuck off with that shit. You are a free citizen of a beautiful country with beautiful, noble and hardworking people. Celebrate with them that you are alive and that you are capable of making a change together and take a day off to consider the things worth waking up every day for without putting your fellow mexicans down for celebrating as well.
