For all their “christianity”, republicans in the US are pretty hypocritical.
Jesus actually teached that everybody deserves to get fed and housed. That everybody deserves healthcare. That people should care for other people in their community. That is essentially the core principles of socialism.
To be clear, OP is not questioning the validity either. You are, and that’s a separate discussion.
If I tell you “playing with fire is risky”, and then you bring up an old book to me where is it written “playing with fire is risky”, the discussion is not about whether I told you that from the book. It is not about whether my advice is valid or the book is valid. The discussion is just that people who had read the book should have already known “playing with fire is risky”.
