Ever walk down the street in the city and a bum comes up to you begging? He can smell and look offensive. Should that be censored?
Yes. My purpose of being there is not to be a begging target, I didn't invite him to approach me, he is, in Internet terms, spamming me.
Ever been on a farm and smell the pigs or the cow manure? That's offensive.
But it is a necessary part of the operation of the farm. It is a direct consequence without which the farm could not function. In Internet terms, it's the annoying login dialog.
Ever see guts at the scene of a car wreck? That's offensive.
That is an unintended side-effect, not desired by anyone and not intentionally inflicted upon me by anyone. In Internet terms, it's lag or slow loading times.
You are comparing completely different things, not understanding that for some of them, there is no reason we should have to endure them (for the record: The proper solution is that the bum doesn't exist, our society is rich enough that every homeless person is a shame to us all)
Get off your ass, unplug, get out there into the real world and get offended! Trust me, it gets easier after the first few times. And you'll probably realized that being offended isn't anywhere near the worst thing that can possibly happen to you
I'm with you on that there's no right to not be offended.
However, I can absolutely want to protect myself from what I don't like. I keep my house clean because I don't like trash and smells. I keep my door closed because I want to decide who I invite in and who not. I don't hang disgusting pictures on my walls, etc.
I can filter my view of the world. You have a right to Free Speech, but not a right to force me to listen. Individual filters are a necessity or we would all drown in spam. What we need to prevent is centrally controlled filters.
