The thing is, life isn't inherently valuable. It's value can only be define by you as an individual. We only matter about as much as we think we matter. People's opinions on life can be shaped by culture, religion, upbringing, and experiences. Along with that, the whole "our life is valuable" crowd is usually very hypocritical. To them, life is only valuable to those who fit their specific set if views and expectations. A lot of them stop caring when it comes to certain demographics, like the prison population, lgbtq+ people, racialized communities, the homeless, etc. This only helps to further how subjective this view and how it needs to stop being treated as a fact.
