Kaepernick and Nike should take some of their millions, buy a book on logic, and look up the "association" fallacy: Because Nazis allegedly used the Betsy Ross flag, everyone who uses it must be a Nazi. And Sir Isaac Newton was gay because he investigated the apparent splitting of white light into rainbow colors. And Noah was gay because he saw the rainbow sign.
If it hasn't happened already, leftists will find a Nazi who agrees with something posted on FR and claim that makes FR a Nazi site.
This is also an example of the "association fallacy:" Because two people have something in common, they are the same.
The gay pride flag is not a rainbow flag. A rainbow has 7 colors - the gay pride flag only has 6. (It is missing indigo I believe).
