Imagine you're in a room you can't get out of. By the nature of aerobic respiration, you're slowly transforming all the oxygen into carbon dioxide. Now imagine there is a running car in the room with you. Do you first shut off the car to prevent it from filling up the room with exhaust and carbon monoxide, or do you give up because there's no point in life?
You can either give up by selling all your belongings and begin to live on the street as a non-tax paying citizen, or you can do something to stop the things that are taking away your freedoms and liberties, or at the very least, do something to make it harder for those that want to take away your freedoms to do so.
I suffer from depression and have had times in life where suicide is a real option, yet I can't imagine how anyone can think "welp, I better give up now because there isn't a point in trying!" There's always an option. Exercise that option.
