Screw target, what about best buy?!?!?  I shop there all the friggin time ....  *sigh*  
However, I do think that Target is deserving of some sh!t slung at them. 
Here's a little more on the whole subject on Towleroad.    To me it is just like Target supporting a hate group like Focus on the Family, to which I would also stop going there.
As someone commented in one of those threads (at the risk of Godwinning himself, I guess), it would be like sending money to Hitler because he had a robust economic policy, even though you had some problems with his "Jew policy."  I have to say I agree, given the nasty things that Minnesota PAC candidate has said.
