Whilst I partly agree with your viewpoint, the term 'hurty words' can and is directed in ways other than incitement to violence.
The kick back against the term has seen many people, such as comedians, script writers, authors, song writers and the public at large, forcibly silenced because of the threat to their lively hood.
To ban words that some find offensive is censorship, censorship is one very slippery slope imho.
Of course we should self censor, do our bit for social cohesion and all that but I personally draw the line at gagging someone simply because some faint hearted snowflake (another modern term)

find words offensive simply because they don't conform to their 'social justice warrior' (yet another one) values.
I still think that politicians wife has been singled out, by an ever increasing authoritarian prime minister and she should be freed immediately.
Anyway, enough said on my part because I really don't want Phil spanking my bottom.
Again!
On second thoughts, I did rather enjoy it, particularly when he used a wet kipper!
