Chris, while I do not like that Facebook appears to be blocking or removing your content, in all fairness, it’s their platform and they set the rules. I am not surprised by this.
This is just another excellent example of why one shouldn’t trust third parties over which you have no control to publish your content on the web.
Guest to my home can no more claim censorship if I ask them from refraining to discuss a topic or ask them to leave because they say things I don't like.
