I'm not a fan of censorship either but I do realise there has to be some in this world because some people just can't control themselves. The people who bitch about it are usually the people who need it. The people that I laugh at are the ones who think censorship should only exist on the other side. "I'm ok with you having a voice unless you disagree with me then you're an idiot and your opinion is not valid so stop sharing it."
A newish trend over the last 10 years or so seems to be the people who claim to say what they want because they "don't have a filter". I'm not sure how many people are actually fitted with a filter, but for most people I know they don't need one they understand the difference between saying something and being a cunt.
