But you aren’t helping them sin by simply doing generic business with them. You are giving them funds with no direction as to what to do. Now the responsibility is theirs before the Lord. It isn’t yours.

Of course you are. Who do you think that money comes from? If you know they fund planned parenthood and HRC.org and you choose them over a company that doesn't, you are choosing to send some of that money to those organizations.

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.
