Why won't the Avengers help the "irrelevant" people?

Also those that the soldiers embrace tend to be people they know and love, Lois is someone Clark barely knows at that point, sure he's into her and vice versa but that's like their first kiss, not exactly a romantic moment or setting to indulge in their sexual attraction to one another because they don't have any emotional connection to justify it the other way around, people may let it go because Lois & Clark are the most iconic superhero comic book couple but going off of the narrative in MOS they are practically strangers.
