Uh, have you even been on Reddit? There are definitely people who want to ban words. But even without going that extreme, Person B in your example is way off-base. There's nothing wrong with Person A, they're just experiencing an unfortunate mental illness. But Person B is creating this moral obligation for everyone to participate in the treatment of Person A's mental illness, and that's an obligation which simply does not exist. It sucks that Person A is sick, and I'd even be happy to devote more of my tax dollars to help them, but I don't think that we should be curtailing our free speech to help treat the vast array of possible mental illnesses we might encounter on the internet.
