This feels like an infinite power glitch. The paradox that happens after showing this picture to nationalist would probably solve the energy crisis. Which would probably make them angry, which would make more energy.
It can be alright if you think your nation's value are worth preserving.
E.g. it is Patriotic to defend your country against a fascit invader that wants to remove your nation's self-determination.
You can welcome an invasion as a liberation force if no patriotism is involved.

At its best, nationalism in some forms can help unify people from disparate backgrounds into an imagined national identity. Unfortunately, most nationalism rots into division instead. Christian nationalism in the US, Hindu nationalism in India, Nazis in Germany. These all reject members of the physical nation in favor of their crazed fantasy version.
Anti-colonial nationalism is fine actually. Not ideal but it is basically "everyone here regardless of more local culture should unite in a combined struggle to overthrow the oppressors" as opposed to colonial nationalism.
Yes. It is normal for your body to have some level of cancer cells, but the immune system constantly keeps cancers in check. As the immune system weakens, cancers are more likely to become problematic. There's even a group of cancer that is so much more likely to happen in AIDS patients that they're known as AIDS-related cancers.
