Excuse my butting in here, but....
2 Corinthians 6:14 (ASV)Be not unequally yoked with unbelievers: for what fellowship have righteousness and iniquity? or what communion hath light with darkness?
I won't shop at target, for example. They're removing the boys and girls department to satisfy the PC crowd [The army of darkness - PC (the doctrines of demons) is the opposite of the 10 Commandments].
I have no problem supporting Hobby Lobby. I know every dollar I spend at these places is like a "vote" for their companies beliefs. I just can't give my "vote" away freely to those I disagree with.
Sure, I'm not perfect by far. I'm sure I'm supporting things I'm unaware of. But I do shun those I know about, and I believe withholding my "vote" from a PC organization is a "vote" for the good guy!
I do my part.
This same Paul said we may purchase meat sacrificed to idols.
