back to one track mantra. "who" can be a pronoun for an idealist or the entire group of idealists sharing same methodology of ignoring how biology works naturally.
"whom" is always signifying an individual displacement within the whole numbers populating the atmosphere at the same time as which one it was in history or still living as part of current events.
Generation gaps are which generation current numbers occupy as biologically achieved in an ever changing population left occupying space now, right here?
