There's many privacy and other laws that affect myself and my neighbours in Europe that concern me, but hate speech has never been one of them.
Perhaps wherever you're from you draw lines differently to how we do it in Europe, with regards to what is socially and morally acceptable to say?
I should add that we also don't have a right to "free speech" in the UK as, say, Americans do, and yet it hasn't forced us to keep our mouths shut.
Maybe that's why he has serious concerns? Funny how it's always valid for Europeans to have concerns about America and its differences, but when it's the other way around it's a barrage of "How dare you?!" (just look at the responses to OPs concerns).
The lines are much blurrier than you are brushing off, especially now that we have post-structuralist definitions of everything. Do you trust the interpretation to be limited to obvious extreme things when people can't agree what terms like woman, inflation, recession, etc mean?
Or, think about what happens when a political party you don't like can use the same legal framework you built with good intentions in ways you probably won't like.
/e: lel, he has been warned by dang already for other comments: "Would you please stop the unsubstantive and/or flamebait comments?". So we don't need to bother.
