How to treat the phenomenon that parents are vegetarian and don't let their children eat meat?

Parents' vegetarianism is an independent choice of adults, which is based on self-cognition and rational judgment. Even mistakes are mistakes that adults can digest and bear. However, children are still relatively young. Due to lack of life experience, parents who are mainly responsible for buying food and cooking at home only eat vegetarian dishes, which may deprive children of the right to choose food in disguise, which is unfavorable to their growth, health and even psychology. So I think this approach is all wet.
