Why doesn't the Christian RIght use the power of the purse and boycott?

I see businesses folding to boycott from homos and other leftist agendas, why not Christians?

Christians have the numbers and if congregations were to unite and say this company xxxx is promoting non Christian beliefs let's boycott I think it would have an effect on the companies. I mean the leftist are doing it right now. Why not the majority on the right?

Use the power of the purse and the network of the church. Take control back of our media and society.

Let's block ads! (Why?)
