I totally agree with you! It seems to me that since in Facebook we keep family, friends and other acquaintances, we tend to be politically correct most of the times, and not always express our opinions as they are.
And yes, I also had this experience as you describe it! I think this is the challenge, in general, letting go of the things and people (or in this case, the social media!) that do not fit into our current values or interests.
Funnily enough, i often found it challenging to be politically correct. I actually think i've probably got more in common with steemians ive never met than some of my old faceschmuck friends.
I left Facebook 18 months ago when they started removing anything politically incorrect, or news stories they didn't want seen that I had posted...
Yeap! Their double moral is quite incomprehensible...!
I'm certainly with you regarding facebook. Just in the process of leaving/exchanging contact details with friends on there. I even felt compelled to write a poem about it! (random I know). https://steemit.com/poetry/@perceptualflaws/goodbye-facebook-an-original-poem
