Why should a society tolerate seditious speech, that seeks to topple the very society that allows it to flourish? Free speech should be used responsibly, to promote the values of a society, not destroy them. Few countries share the extremist US point of view of allowing all speech (with few exceptions, e.g. libel and true threats). Instead, they approach it more maturely, to safeguard their values and not allow extremism to take hold.
It saddens me I have to explicitly tag this as sarcasm.
