Life is not a rainbow and people are not Saints. Throughout history, there have been many symbols that stood for causes and beliefs that have always been insulting for a specific group of people and/or the whole world.
1. The Fleur-de-lis is a symbol that was used in the 13th century by rich families invested in the slave trade.
2. A simple jigsaw puzzle can be offensive, since it shows that an autistic person does not fit in.
A complete puzzle is the more accurate symbol if you want to support autism.
3. The swastika was used from Adolf Hitler as a symbol of his dictatorship and murderous politic stand.
It’s a very old symbol, that has been used by many civilizations, but not for negative reasons.
