I have been following "Lefteous Indignation" on Facebook. Just a little while ago I posted a comment on one of their posts. I challenged the validity of the information in the article and asked for corroboration of the data. The post in question stated that 15% of Americans are gluten intolerant, but there was no research data given to back up that statement. The end of the article recommended people contact a homeopathic physician to get a good workup and treatment for possible gluten intolerance.
I stated that homeopathic medicine was bogus and unscientific and said that I hoped people on the left didn't fall into the same mindset as people on the right with their climate change denial and anti-evolution attitudes. That apparently hurt their feelings and made them mad.
I was shocked when less than as hour later my comment had been deleted, and I also had been permanently blocked from their Facebook page. They have fixed it so I will not be able to comment on any further posts they make or contact them in any way. I'm still stunned that my comment had such an effect on whoever manages that page that they would go to such length to stifle free speech and honest debate.
What's especially galling to me is their claim on the top of their site on Facebook: "Fact-based critical thinking. Syllogistic logical argument. Humanity-driven analysis."
I did have a moment of satisfaction when I saw that someone else also just commented and challenged the data they presented in that article. I'll see how long that person's comment is allowed to stand. "Heil Hitler Syndrome"???
