It is a lame excuse to say he didn't know about the anti-gay stance of this group, as many have pointed out a simple Google search shows many examples of their anti-gay beliefs. Blake's apology also stops short of actually apologizing to supporters of gay rights. Until Blake speaks out and clearly states that he is not anti-gay rights, I will not buy another pair of Toms. It is his right to have his opinion, whatever his opinion is, but it is equally my right to take my business elsewhere if I don't agree with his views.
There are plenty of others ways of supporting those who need assistance, such as direct donations to non-profits.
I'm tossing my Toms!
