Oh my, that'll show 'em.
Actually, posting on Facebook a conservative position will PO them. My liberal sister was always complaining because Sarah Palin showed on her sidebar, when I joined a Sarah Palin group.
When I posted an article about the horrors of socialized medicine in Great Britain she posted snarky comments. I would respond and she delete her comments - it looked like I was talking to myself.
I temporarily closed my Facebook. When I returned, I announced that this would be used by me “first and foremost for following campaigns AND I was a conservative not ever to be reformed. Leave if you are uncomfortable, it will not hurt my feeling.”
Some did leave. I was relieved and felt liberated.
