When I search for "Candace Owens is a fraud" I get plenty of links to articles that have nothing but more JB style rants. They claim that she's a fraud because she changed from leftist anti-Trump to a conservative in less than 2 years. The more one thinks about this, the more damning it is to the left.
What kind of people change their political view so diametrically in such short order? Answer: people who have been brainwashed and suddenly realize it. Imagine a Nazi youth, or a young North Korean - brought up in an environment where they were taught that one particular world view was the right one and that those who oppose that view were bad people.
There's the answer why people suddenly abandon the left. They continue until what they see and experience contradicts what they are told on a daily basis. And they realize that once they abandon all the complicated rationalizations and lies that support their world view, everything makes much more sense.
We call it waking up. It's what people do after they realize that being "woke" means they are still sleeping.
