NTU graduate valedictorian using the 'f' word in her graduation speech

In the recent case reported in the newspaper, a graduate who was a valedictorian, Trinetta Chong, used the 'f' word in the graduation speech. This then brought about a huge hooha, of which some criticized her and others who felt that it was nothing much.

In my opinion,I feel that it was nothing much. Firstly, the 'f' word could be used to refer to both a positive or an insulting term. In this case, she used it for a positive cause, which is to congratulate her other graduation mates, and not to insult or defame another person. 

Next, as the world becomes more modernized, the society is becoming more accepting, and in most parts of the world, using the 'f' word is no longer a great deal unless used to insult others. 

Next, she could have accidentally used it as it was one of the biggest events in her life as she wanted to express herself.Last but not least, the speech was meant for the other graduates, and since they have accepted it, I think that it is the alright.

All in all, I feel that it was not wrong of her to use such a word in this context.
