I suspect the same number of people were upset in 2006 as would be upset in 2017. But there wasn't a social media platform for those upset views to be expressed and easily measured.

This idea of "oh everyone is offended these days" is a bit weird to me; the 'these days' part I mean. There was a lot of comedy from the past that was... awkward to me as a kid, or just... felt unnecessarily cruel. But I was in a minority, or at least felt like it, with some of those. And... I don't think I changed, but I now can hear/read about others who share the same sensibilities on comedic topics.

The notion that it's somehow "more" people getting "offended" today just strikes me as odd. It may be that as more folks have a platform to share their views, that influences some folks, but I'm not sure that works on all topics. Certainly... on comedy, I've heard many of complaints about some comics/topics. Rarely has anyone's view of a comedy bit made me change my position. If I found it cringe/bad, I found it cringe/bad.
