I feel like some of the eat the rich-type rhetoric you see on reddit would be much less acceptable a decade ago.

Edit: i misread your comment as the opposite of what it said and am confused. I am not claiming that i believe left-wing views that used to be acceptable are not anymore. I am claiming i see people say all the time that the right end of the overton window has expanded out so that right wing views that used to be unacceptable are acceptable now (which i agree with, but i think the same could be said for the left, maybe not to the same extent).
