To continue on a little, the issue is that the practices of many of these flawed philosophies are rising again at an increasing rate. Perhaps it is because of the dilution of the term through a lack of understanding of the reality of what they stood for. History repeats for reasons.

How I see it is that if words such as these are allowed to be diluted, when the reality of the past arrives again, people will not recognise it for what it is and think it is something new when in actual fact it is just a reiteration we no longer have a word for.
