I know a few threads on this have said this is not a freedom of speech issue as such, because government is not denying him any rights here.
Is this a reflection of what a politically correct world we live in? Anybody who says anything which can be perceived as dissing officially recognized grievance groups, will be targeted for destruction.
Then there is the issue of consequences for exercising freedom of speech. Government is not going to punish him, but others are going to.
Trial by PC lynch mob.
There is a precedent, though.
Anyone remember Marge Schott?
