US democracy did just fine for a few hundred years before socially irresponsible media.
You can chart the decline of political discourse and the rise of wack job violence with the rise of social irresponsible media. As they are now, allowing any and all speech that would be illegal or never published by any press, or other medial outlet, they are a cancer. Nothing good has come from socially irresponsible media, except stupid cat pictures and inane 'here is what I am eating drivel.'
This mass moron infestation will continue to be a serious threat to civilization until 230 is revoked and social media platforms fall under the same rules as other media.
