There is almost certainly anti-conservative bias among major social media companies but it’s not generally from things controlled by purely automated or mostly automated algorithms like Google Search. It comes more in the form of human moderation for things like “Hate Speech” or TOS violations. This can even show up in routines that are semi-automated when human moderators set up a list of terms to flag and which ones not to flag. Those sorts of things can and are heavily subject to bias.
Things like bans and shadow bans, sites like “Patriot Prayer” being blocked or taken down for “Hate Speech” but Antifa not, Jihad Watch being blocked by content filters but Hammas being allowed through, etc.
The bias IS real and it’s serious….and almost all Conservatives who have operated in the digital world have experienced it themselves… but it’s not in the algorithms themselves or in the search rankings.
