Claig. You might not like this. Some people do hate other people, for their own peculiar reasons. The WORDS they use, when expressing hatred, make absolutely NO difference to the sentiment.
If those yobs had yelled "Like your coat, Missus!" at that woman, with the same feeling, then that woman would have been just as upset. Being hated hurts: it doesn't matter what words are used to show it.
You seem to hate (or, at least, despise) ad execs and Guardian readers. Apart from your idiosyncratic use of the term "creative officers", you haven't used loaded words about them but your loathing shows through anyway. My nephews know they're not allowed to use "spastic" as an insult, so they say "scoper" - to mean the same thing. Change the words, you change nothing.
By fixating on the term "Freak of Nature", you seem to be making the following assumptions:
1] World-class athletes are vulnerable bunnies, who need to be protected from words you dislike.
2] A Paralympian could not be freakishly gifted, the word freak must refer to their disabilities.
3] Freak is an insult.
4] Disabled people are incapable of making informed choices about the ads they're invited to take part in.
5] Advertising professionals are capable of mind control.
Plus, as an aside, [6] Ad execs read the Guardian! (Very few do)
I disagree with all of your assumptions.
