I agree with your comment, I just want to point out that I am explicitly against capital punishment, without disagreeing with you. And also that the reason for the demographic spread is that this is the demographic spread of the community you are talking about.
Also, while I am against capital punishment, if it had to be used, it should always be nitrogen gas, it is not untested, it is very well tested to cause no pain what so ever to subjects almost suffocating from it.
