Without some risk we'll get nowhere.
A lawsuit is most often like playing roulette. You never know how the judge will decide although of course you try to make him decide in your favor. Mostly judges, authorities and their experts stick together. That makes it even more difficult, but less roulette. (That's not a positive for us.)
One negative verdict, which might be a precedence, doesn't mean it's over. The same holds for a positive verdict. (Unless maybe the verdict was spoken by the highest court. But then the fight continues, maybe not before court.) In a war there are always several battles. Since the discrimination against us is systemic we will need to fight many battles, e.g. several lawsuits could be needed, over many years, by many people.
