No. I do not flag or censor things at all under regular circumstances because I actually practice the belief that it is in fact a human right to free expression unless it is aggressively abusive or actually threatening. I will also tolerate regular harsh and abusive words and in most cases if I don’t tolerate it I will just not read it or look away or even just block. I’m not vindictive like most people seem to be today where an ideological mob forms to suppress heretical ideas that their herding instincts compel them to suppress in order to be a good member of the herd.
You're surely more knowledgeable than the author about America and Europe, but he's not commenting about the differences of those two things.
He's only remarking that he's observed a general difference in the mindsets in the two cultures.
As pointed out by another comment, it's a fairly broad observation that many have noticed.
