BAD IDEA
Can I call someone far right a venturinha?
You can, but expect a verbal slapback unless you’re fun at parties.
Calling someone from the far right 'venturinha' is basically tossing a verbal grenade into a political minefield. Unless your goal is to get into a shouting match or ruin your social standing, it’s a terrible idea. Insulting loaded political beliefs rarely earns respect or wins debates, just more drama.
