Richard Grenell has a great point. But, let's take it to the next level…
Beyond keeping people from openly supporting LEOs, MAGA, saying that "All Lives Matter" or supporting non-liberal politics (BLM's operators are openly Marxist), the Goodyear guidelines also keep people from seeing just how many Black people and gay people support Trump, LEOs, and MAGA.
The Left wants to pretend that (gay) people like Scott Pressler and Brandon Straka don't exist.
They want to pretend that (Black) people like Candace Owens and Diamond & Silk are just "fringe" exceptions.
The Left wants to proclaim themselves "the party of gay people" and "the party of Black people." Then they want to pressure gay and Black people into conforming to the expectation that they vote Left, too.
Remember what Q said about making it seem like extreme Leftists are the majority, when they're really the minority? A lot of this is about social pressure to conform. Lots of normies don't have the fortitude to go against the crowd.
But, that only works until people realize just how many Black and gay people are behind LEOs, MAGA, and Trump.
