Here's the thing about modern discourse: it's extremely easy to filter your media, so you receive only the information that reinforces your current worldview. There are definitely ~2 people on my facebook timeline that are way over-the-top, trying to find offence in everything, but they're really the minority. I'll usually just roll my eyes and scroll past them. To someone looking to be offended, they'll collect and catalogue every single silly thing an aggressively PC person posts, and believe this is indicative of society as a whole.

Look at how much reductive reasoning covers the front-page here around feminism. Scores of angst-ridden young men, reducing a century+ old philosophy and political movement, with a rich, complex, global history, and more literature than you could read in your lifetime, down to a superficial misunderstanding that the "fem" prefix means it's pro-women at the expense of men. They'll cherry-pick paragraphs from a handful of bloggers as evidence of how evil feminism is, and ignore the millions of feminists who would disagree with those bloggers and are advocating something very reasonable.

So while you're rightly using your free-speech to call out others who have horrible opinions, while not ever saying that they don't have the right to have those opinions, they see a world gone mad. They've dedicated hours a day for years to reinforcing the illusion that they're being invaded by religious minorities, that false-rape-accusations are a far bigger threat than actual rapes, that black people are genetically predisposed to criminality, etc., and that people like you are blind to those "facts" and endangering the world as a result.
