How should I call them?

tdol, I appreciate your reply.
This is very complicated indeed, but this is mainly about the world knowledge rathr than the knowledge of English.
I've thought that those who are against abortion are also against the death penalty, but I've learned it is not the case. Also I've learned a lot about the gap between the US and the UK about the pros and cons of the death penalty. Thanks.

You're welcome.
