You may have to realize that sometimes humor is the way to cope. It’s why there are Hitler and Auswitz and rape jokes. Poor taste? Maybe, but sometimes people joke to either point out the tragedy, to make people think about a tragedy, or sometimes plainly because it’s better to laugh then vry about literally everything bad because then you just get into a depression.

You do not get to tell others how to respond to situation. You may not like how one person responds, other may not like how you respond.

I too respond with humor to death. Not bect I don’t care or because I’m 15, it’s because I’ve seen too much of it. I’ve seen people hanging from bridges, I’ve seen people on pieces, I’ve seen people dying in front of my eyes. I’ve seen the war deaths on tv, I see Trump, I see the inevitable horrible climate change… Either I joke laugh about it to give it a place, or I might as well kill myself and get it over with.

You do not get to tell me I’m wrong, you do not get to tell me I cannot make jokes. If you don’t like it, you can ignore it. Grow some skin, learn about life, not everyone is like you.
