First of all, you should know that it’s completely okay to paint your nails. Men can paint nails too. And if you will see many celebrities and idols are painting their nails too. It’s nothing wrong in doing that. And these are just fake stereotypes that are set by society. But unfortunately, you can’t file a complaint against them for bullying you unless it’s not life-threatening. You can just try to avoid them as much as possible. Try not to pick a fight with them. Try to stay in crowded places, so they won’t try to hurt you.
