You are at liberty to ignore them, if they bother you. (I routinely ignore threads about, e.g., football - but have never felt the need to complain.)
Also: Because the biggest, most-dangerous land war in Europe since the conclusion of WWII is currently underway, and in danger of spreading. Because Putin has violated the principle of the inviolability of international boundaries in Europe established at the close of WWII. Because Putin is a monster who has caused the deaths of many hundreds of thousands of people, and that is slightly more important than arguing about NFL line-ups.
Again: You are free to simply ignore these threads if they interfere with your enjoyment of talk about baseball scores.
