It is fine with me if you did say I was pro-choice. I'm not ashamed of my stance on a woman's right to make her own decisions about her own body, no matter what the circumstance. If that decision is abortion, that is her right and concern, not anyone else's, in my opinion.
Personally, I don't see the connection between pro-choice and the separation of immigrant children from their parents, but you obviously do, and that is certainly your right. Each of us has opinions based upon experience, religious beliefs, or other contributing factors.
