Three biggest Democrat Hoaxes in our lifetime:
1) Judge Kavanaugh groped Christine Ford
2) Trump colluded with Russians to beat Hillary
3) Global Warming
Nice list the first one is whimsical, the second happens to be true with the proviso that collusion isn't a crime and the third is mistitled. Global warming is the hook for suckers, climate change is real proven science. That said, let me take a crack at this biggest hoax in our lifetimes thing from the other side.
Three of the bigger Republican hoaxes in our lifetime:
1. Convincing poor Euro-Americans that they were middle class, while convincing middle class Euro-Americans that they belonged to the wealthier class, then convincing all of them that all of their issues came form people who didn't look like them in order to get them to vote against their own best interest.
2. Duped the general public into believing that the World Trade Center fell because of the efforts of Iraqi's and Iranians. This ends up costing to date, thousands of lives and billions of dollars in a hunt for weapons of mass destruction while the real perpetrators, the Saudi's walked free.
3. Created an atmosphere in which crack cocaine could be introduced into poor African American neighborhoods which set the groundwork for the population explosion in the PIC (prison industrial complex). A make work program that still feeds upon criminalizing the desperation that comes with being poor. (see: war on drugs)
