I'll say it out loud - I really don't like standing for the national anthem sometimes. The entire thing is in a dialect I only half-understand, and even the parts that I do understand, they sound rather hollow at times. Then there's the entire business of realism and objectivity - the national anthem is a paean to our great nation and, let's admit it, we don't always feel the love. I, atleast, don't.
There are times when I want to protest, when I want to make a statement and times when I simply find the entire process of mechanically standing up to the national anthem and the accentuated action of saluting the national flag boisterous and showman-ly. It's not the way I want to pay respect to my nation.
But, ironically, that's exactly what I'm not only supposed to do, but also compelled to do (by law).
True respect can never be forced, or so I think. Only when you have people standing up for the national anthem and saluting the national flag, when they could have been doing anything else at the time, do you and those people themselves feel the genuineness of their respect and pride.
There should be nothing wrong with flag-burning or wearing the three colours on your person. Or the point of the tricolour standing for freedom (of speech and expression, amongst other things) becomes somewhat moot.
