If you can’t find a big chain or manufacturer who openly espouses conservative moral standards, go smaller.
For the new fridge, look for a mom-and-pop or local dealer. Failing that, try to buy through a right-minded sales rep who works on commission. Same with the vehicle — find a dealership run by good folks.
Keep your $ out of the wrong hands.
I do a lot of that already. In the next three years or so we'll be replacing our central heat and air unit. I have a really GREAT family run heat and air vendor that will do the work. Unfortunately, most of the money will actually be for the unit itself. I find nothing on any of the major vendor's websites (Trane, Carrier, etc) that indicates any philosophy.
Sadly, I have a feeling that one or more of these are run by people we support, but they keep their beliefs to themselves to avoid having the nut-ball faction marching outside their buildings. That's what really pisses me off. People can express brain-dead liberal ideas and get away with it, but if you express conservative values, the freak circus shows up.
