This is can be seen in any number of areas:

- the Gun Emoji censorship was only the beginning but clearly intends to define the ideologically playing field by limiting the ideas people can express

- Those who believe that "hate speech" should be censored will likely view the censorship in place as legitimate. However, "hate speech" is typically allowed against Whites (they are considered "oppressors" and because of power imbalances, it's different for them ... ). The phrase "Hate Speech" is used to ban speech that did not violate previous norms against violence / obscenity but is nonetheless considered subversive.

- Facebook contracted with the "mainstream media" and recently eliminated its "trending" feature after left-wing criticism that they did not censor conservative so-called "fake news" that helped Trump win election. Apple is similarly contracting with predominantly left-wing "mainstream media" outlets to stock its human-curated i.e. censored News App.

- Youtube and likely others work with ADL / SPLC to use ML to algorithmically flag and ban "hate speech" content.

Here is a ranking of the subreddits ADL flagged in "Hate comments count by subreddit":

- White rights

- Mens rights

- the Donald

- Ask Trump Supporters

- Republican

- Conspiracy

- Guns are Cool

- New Right

- 2016 Elections

- Censorship

- First Amendment

- Nazi Hunting

- 911 Truth

- Good Cop Free Donut

They appear to be very focused on right-wing "hate" and not much on the left.

- ADL is working with social media giants (notably Reddit) on automated "hate speech" censorship. https://www.adl.org/resources/reports/the-online-hate-index

... the OHI model captures the experience of hate speech online – it does not define hate speech [it's based on subjective manual flaggers rather than explicit criteria]

...the D-Lab is identifying strategies to scale the process for labeling comments.

While there is still a long way to go with artificial intelligence and machine learning-based solutions, ADL and the D-Lab believe these technologies can go a long way to curbing online hate speech. [i.e., we hope ML-automated censorship will be effective].

The ADL’s long standing mission has been to stop the defamation of the Jewish people and secure justice and fair treatment to all...the Online Hate Index will help us do just that.

- ADL [of B'nai B'rith] was founded in 1913 by B'nai B'rith, a "force for Jewish unity, Jewish security, and Jewish continuity." (http://www.bnaibrith.org/giving.html, https://en.wikipedia.org/wiki/Anti-Defamation_League)

- Youtube demonetized, suspended, and terminated numerous gun channels in recent months

- Pervasive political censorship of controversial but nonviolent "alt-right" ideas, e.g. Twitter and Jared Taylor, Richard Spencer and crowdfunding. Certainly neither constitutes "incitement" under the first amendment standard of Brandenburg v. Ohio "directed to inciting or producing imminent lawless action and is likely to incite or produce such action."

- While private organizations are not bound by the first amendment, one could reasonably consider their removal of political speech that in public is protected by first amendment to be censorship.
