Good God.
After reading this thread -
You are forced to pay to attest your age, because as a society we have decided not to, or are unable to, end social media firms and porn sites.
At the same time, we have decided that the harms that occur to kids and teens need to be mitigated.
No. My question was not why am I forced to pay, my question was why should I pay. Obviously if I have to pay, I will (that's a logical necessity, because if I could avoid it then it was untrue that I had to, to begin with). Why should I pay? That is to say, by what mechanism am I saddled with the moral responsibility that justifies me having to spend my money to protect someone else's children? Given your line of argumentation, I'm going to guess that you don't have an answer to this question; your answer is that I should GFMS and just pay. Prove me wrong.
