Life is a journey, the trail may take us to our next destination; but, don't ever forget our root.  However, there are many who have the tendecy to look back and start criticising their beginning, be it their 'original' religion, culture, custom, language or even their 'home country'.  It is because they've fallen head over heel in love with their new found 'home'.
However, that doesn't give them the liberty to simply criticise their home country.  In fact, those who have made the criticism are not knowledgeable enough to do so.  They don't have enough knowledge about their own country, even though they might be born there, besides they are still under the spell of the colonial mentality.
