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.
If your argument is that the whole bible is unreliable due to canon selection that’s a totally viable argument to make. But that then goes both ways and means that you can’t make an argument about anything Christ did or did not teach or do. It means, you can neither make the argument that Jesus was for eating animals or against it, because any scripture supporting any of these points was subject to canon selection and thus is unreliable.
Of course the whole thing is unreliable, due to selection. Still there was a selection done. You are almost there.
