The actual 'grown up' take.

Absolutely. I would say that not liking onions is a bit of an illusion though. They really are in everything and are so elemental to cooking. I think if people understood this better they wouldn’t fear onions so much. Sometimes fear of onions is also part of a generalized “zero seasoning” palette common among some older white Americans, where even black pepper is considered “spicy” and most food is totally flavorless and usually cooked to a pulp. It’s not about growing up… this palette is just missing out on so much happiness in the world. Being just a tiny bit brave with food is a wonderful decision to make in life.
