I completely agree with the first statement. I am not so sure about the second one. Learning ideas and concepts is a sort of additive process - hopefully learning one will not subtract away something you already had. Having been exposed to an idea which cannot be expressed in English now gives your brain multiple interpretations to choose from - that is, something which might be considered a real mistake in one culture (e.g. society judging individualism) might be more acceptable to you if you were a part of another culture (e.g. where society did judge individualism but also compensated by being more supportive of failure in general without creating indirect social safety nets which can be interpreted as one generation stealing the others' wealth). The concept of suicide, for example, is a good example of learning a bad idea, but it should hopefully be balanced by the other ideas you have learnt too.
