Why the hate for wisdom?

[unity100]

Before i go to bed, lets take a second to illustrate freedom of speech vs hate speech in simple examples.

Free speech:

"Mexican immigrants should immigrate through legal channels and do their best to integrate into US society while also maintaining their cultural traits"

Hate speech:

"These mexicans are leeches! They come here and freeload! Their culture is incompatible with ours! (whose?) We should teach them a lesson! They deserve what's coming to them!"

.....

As you can see, in the first half of the narrative the 'others' have been separated and dehumanized, in the second part there is practically overt 'justified hostility' and calls to outright negative and aggressive behavior.
