Because it’s framed differently. The Democratic base don’t consider themselves to have thrown a “shitfest” over Keystone XL, and don’t consider Biden’s day 1 executive order killing it to be “red meat”.
California, for example, is currently pursuing a lawsuit (https://oag.ca.gov/news/press-releases/attorney-general-bont...) seeking to force Catholic hospitals to perform abortions. That's a controversial position on a high-profile issue whose opponents consider it to be outrageous persecution. Would you say this is an example of "shitfest red meat"? Or do you think that it's just an ordinary lawsuit, because you're not personally outraged by it, because you think California's position is reasonable?
