Most people are more than aware of the liberal bias of the major social networks. If they follow the news, they will be aware of the removal of many conservative Facebook pages such as Right Wing News, Warriors for Christ (which is back but under severe threat of closure again) as well as fringe right wingers such as Alex Jones. Just recently it was noted that Louis Farrakhan called Jews termites on Twitter and that was not hate speech according to them. Yet they are quick to remove the posts of pro-life groups and those defending the biblical definition of marriage. There is clearly a double standard and one that I believe to be deliberate. A deliberate attempt to control the information that is seen. This is also evidenced by pages that though they haven't been banned, have been 'shadow banned'. In essence their reach is curtailed so they post as much as they want but barely anybody sees it. Even if they follow the page. Christians and conservatives are not welcome on the major social media platforms and this has been made clear time and again. What should we do about this? Leave.
There are other social network available that are quite welcoming to Christians.
Mewe is perhaps the most refined of the alternative social networks. It has a decent website as well as Android and iPhone app. It also supports groups, private chat, has no algorithm at all, zero censorship and is self policing. If you have an issue with somebody, you talk to an admin of the group you're in if applicable, block the person or if need be call the police. Mewe is totally hands off in their moderation. We have a group there and you are encouraged to join it.
I mentioned Warriors for Christ and this is their social network. It has pages and yes we are there as well. It supports chats and groups but there is no app other than an Android web app. They say a proper app is coming in around a month but it was supposed to be done in August.
The newest one on the list, it got into a few of the conservative news sources. So far it looks pretty good and supports groups, pages, chat and even allows you to sell things. We can be found here
All networks mentioned allow the upload of photos, some allow audio and video. I recomend Mewe for now but if you wish to join all three, even better. Watch them grow or fail and you'll still have a back up. Last but not least, British Channel 4 aired a revealing documentary of how Facebook operates. Some pages actually earn them too much money so they are more immune to penalty and are allowed to flout the rules.
