What matters is the actual observable scientific facts
This is a centuries old debate about empiricism vs rationalism. Take some time to learn about it. Ultimately though, science has limits. One thing I often hear is that science can't prove anything; it can only disprove things. The point I'm making is that we can't prove religion is not real, nor can we prove it is real. Yet, people believe it to be real. Likewise, you can show measurable things like deaths caused by cars. However, that does not justify imposing your will on other people. What are you measuring those deaths against? Given that almost every person owns a car and drives daily, is the issue moot? Am I wrong for driving a vehicle if another person gets into an accident?
The internet is one of the biggest tools used by sex traffickers and pedophiles. Should you smash your computer? Does it make it okay for you to smash another person’s computer who has nothing to do with any of that?
Science has limits. It can't solve questions that do not have measurable or empirical evidence. It can't provide answers to moral, ethical, and existential questions that are deeply personal and subjective. These questions often require us to draw on philosophy, religion, and personal values to find meaning and make decisions.
Things that are not measurable or lack empirical evidence are not necessarily any less real than anything else. You can't prove why two people are in love. You can measure process and hormones in the brain and body. You can't scientifically explain why. You can't measure consciousness so is that not real? Are we just brains inside a jar floating in space hallucinating all of this?
Hell trusting that science is the be all end all is a belief itself.
All that to say that taking the position that you have a right to tell others how to live is an asshole position. Sometimes its necessary but its easy to go too far even if you think you're doing good.
