Well, if they dont know better, than thats something to talk about, so they actually can now better.
And I dont really "blame" anyone, I only blame those on the top of it all. The media that forms those opinions for simple minded people, alot of content creators on youtube etc.. I may not be american myself, but I spend alot of time on various platforms, so I can get an inside into certain thinks.
For example things like Breitbart news or certain newsshows on TV. Its really close to hatespeech at times.
I personally enjoy late night shows such as Stephen Colbert, Trevor Noah and Seth Meyers. I know, that those have an agenda on theire own aswell, but to me this has always appeared constructive, while their counterpart is usually destructive and based on instincts. The late night shows tend to be alot more complex in my eyes, especially when it comes to politics.
