JWs talk less and less about blood as their case is impossibly convoluted:
1. All plasma fractions are a conscience matter but plasma as a major component is not
2. Many pharmaceutical companies add horseshoe crab blood to their drugs as an indicator for bacterial contamination - WTC silent on the matter
3.Some HLC can explain WTC positions but most can only follow what they are told
4. White blood cells from mom are found in abundance in mother's milk
I could go on but I will not - my stomach begins to turn...
