There are more than 100k people employed to censor the internet of the things you point out, amongst others.
It is important to recognize that ALL of us self censor. Whether we decline to view porn, or fluffy bunnies, we choose what to not include in our content.
I do not agree with censorship being imposed on free people - for any reason. Even the argument that people wouldn't make offensive images if there was no market for them is inadequate to justify censorship, as there are more appropriate means of preventing those images from being made - and that is where the actual laws belong.
Indeed, by censoring things, those producing censored content are driven to undertake cryptic means to distribute it, making enforcement of laws against such criminal acts as are being censored vastly more difficult.
In the final analysis, censorship is simply adding a problem to the problems those advocating it are seeking to solve.
Thanks!
And that's the key difference - individual discernment versus dictatorial censorship.
