Why should expats teach their mother tongue to their children?

This question does not arise to speakers of English and a few other European languages. This question is mostly asked by some Indians or people who have a sort of inferiority about everything that belongs to them. Some do not even ask but assume that teaching non English/non-European language will actually trouble their kids and that they should "fit-in". Parents and some children assume this in fact is "modernity". i.e abandoning your roots and learnings associated with your people makes you modern!

To put it shortly, my parents put a lot of effort into teaching me more languages: even some languages they could not speak. They made sure I learnt Kannada English Hindi and Sanskrit! If I do not teach my children languages I know that will be huge deception. I should strive to teach them more than I know like my parents did. At the very least I should teach them what I know. Otherwise, as a parent I am cheating my children and snatching the opportunity from them.

The choice is yours! Do you want to teach your children your mother tongue or you would rather cheat them based on your definition of what is "enough". Imagine what would have happened to you if parents decided you did not need what you use today? Teaching less is easy teaching more is hard but good and also an obligation.
