Your environment is not neutral, if you live in a Capitalist country, they will be dragged along the Liberal path without even being aware of it, in order to actually "have a choice" they'd need to be taught Communism (Marxism Leninism specifically because it is scientific, Communism is not a religion), or they would even have the ability to "choose" in the first place.

Additionally, this question is a bit like "should I teach my kid about the deadly snakes hiding under that rock over there or should I let them find out for themselves?" This stuff isn't like choosing what color you want your car, there are objectively correct and incorrect answers, and the consequences are deadly serious.

Edit: "wouldn't even have the ability"
