Why don't you contact him through his social media channels and tell him that you think that he, his friends, his family members, co-workers (
<url removed>) and all his fans/followers on social media with whom he interacts through social media on a daily base, should immediately stop calling him or refer to him as "anão" (midget/dwarf/leprechaun), because
you are sure that he will not appreciate his own words and those of the all the people interacting with him who call him or refer him like that. It doesn't or shouldn't matter what he thinks, because you're sure that you know him better than he knows himself.
Maybe while you're at it, also express your concerns and tell him that he should not appreciate enjoying himself when he's booked every other weekend in the clubs across the region when he's one of the main dancers or hosts dressed like a leprechaun (see pics), and that he should not enjoy himself wearing the same clothing when he goes to afterparties in the city. Because you're more sure than he
himself is about what he appreciates or should appreciate when he (or all the people around him and/or interacting with him) refer him(self) as an anão.
In the meantime, Pistolinha posted a new pic on his verified profile that he maintains daily.
He named the pic: "Anão pauzudo" (oops).
<url removed>Pistolinha is waiting for girls to come online. He logs in every day on his official cam site @ "Pistonlinha Anão" (oops)
https://cameraprive.com/br/pistolinha-anaoPeople here are interested in porn, not in political correctness going overboard in a case of some assumed and already debunked opinion.
But, I'm sure he appreciates you expressing your concerns about what you think he should or should not appreciate when he markets himself as: "Anão pauzudo", "Pistonlinha Anão" etc.
