I will only address point No. 3.
The media has been very sympathetic to these protests, and I'm not referring to what overtly Communist media you follow. I'm referring to the MSM. Nearly every article that spams my yahoo feed from the alphabet media, CNN, NYT, etc, etc, has a "balanced" assessment that is specifically designed to garner sympathy for the protesters- the slant is subtle, granted, but it's definitely in favor of the morons . Now, I do agree with you that they're wanting to protect Biden. The strategy is to guide sympathy to these idiots, so that the protests do NOT damage Biden.
