She's the Canadian biological male who played her trans card (IE: claiming to be a woman) to coerce beauty salons into waxing her genitals. He thought that since these salons offered Brazilian wax for female genitals, then he should qualify since he identified as a woman (yes, flawed logic). All of the salons that he visited declined. Some were for religious reasons. Most of them was due to practical reason: waxing a man's genitals require extra care, and the salon workers either didn't have the training, or didn't feel confident about the service's quality.

Yaniv took several of those salons to the human rights tribunal. This is how bad the PR was:

• The tribunal has a history of being a kangaroo court. For example, they almost always rule in favour of the plaintiff. In this case, they ruled against Yaniv.
• Even SJWs, lefties, and commie trans supporters denounced Yaniv.

What can we learn from this story in our culture war

• Use examples that require very little research. Remember, you're dealing with normies who don't follow the news as much as you do. Don't give them a topic that requires them to research months worth of news stories. This Yaniv story doesn't require any more background knowledge than the story itself.
• Pick an issue that even lefties can agree with you. EG: it's wrong to nefariously play the trans card.
