The PC culture of the far left has gone extremely radical in the past 5 years or so. It seems as though anything that you can possibly portray or publish will be offensive to someone, and therefore not acceptable. The level of offense has also steeped to stupendous levels. At this point people can get offended by people that are "too fit", or "too privileged". It almost became a culture of shielding yourself from your own failures. Ironically it has became identical to the far right ideologies where your race, gender, and other things you have no control of will define you as a person in their eyes, regardless of their socioeconomic standing, or personal beliefs and ideals. Being white is a sin, being male is a sin, following your culture is a sin, everything is problematic. That is perhaps why such a minute thing as a $100 banknote can be blown out of proportion.
PC has definitely gone way too far in my opinion. These days, people are getting offended over absolutely everything, like the whole Starbucks cup debate. It has really become just silly and ridiculous and I think it just looks like a three ring circus instead of people being respectful and non-offensive. To me, it offends me more to see people so outraged over silly little things than it would if they just kept quiet. By all means, if someone uses a racial slur or something like that, you should be outraged. But getting offended over what picture Canada chooses to print on their money is just plain silly.
There is a fine line between being 'politically correct' and being ridiculous. There are people who will stop at nothing to find something wrong with anything! Sometimes we just need to stop and let things be. It's gotten to the point that nothing is safe from criticism anymore, and everybody is walking on eggshells so as not to offend another.
Most believe that political correctness has gone too far. It is understandable that some might be offended by the image of an Asian woman using a microscope on the back of a $100 Canadian banknote. However, when the image was replaced with a Caucasian woman, there were still complaints of discrimination. In short, because of political correctness, it is impossible to please everybody.
