This is anthropomorphic thinking. But in order to express the concept that aggressions and other interactions could increase toward species who have built their overinflated infrastructures across migration paths, territories or outright destroyed swathes of habitat of other species, yeh they probably are hella angry at these stupid hairless apes.
But the old farts are growing in numbers, so to what degree were conservatives always that way, in other words are people becoming newly/more conservative about immigrants in their old age, or will the more liberal young ones of today bring this more open attitude into their old age , lessening conservatism over time?
