"I don’t need feminism because… [insert ignorant misconception about feminism]"
Sure. You yourself said it: you don’t need feminism. But women in most countries around the world do, and all women in your first-world country have also experienced slut-shaming, sexist jokes, rape culture, objectification, dehumanization, etc. So go ahead and put your ignorant little “I don’t need feminism” sign on the internet. But this is just not about you.
