Tolerate intolerance?

The sticker that really gets me mad.

Some new neighbors moved in recently.  I haven't met them.  Based on their bumper stickers, I'm not sure I should.

Perhaps I'm making an incorrect assumption about its meaning. Each time I see it, all I think is that it must be a response to the popular equality sticker from the Human Rights Campaign.  The unequal sticker appears on their car which also has a giant "GOD" decal on the rear window promoting some kind of mission organization.  This combination of stickers was another reason for my assumption that this is a symbol of support for DOMA; support of no marriage rights for gays.

So, here I am.  I'm making assumptions about neighbors I never even met based on stickers on their car. Their sticker makes me upset because I think it shows intolerance and hate.  Does my judgment of them make me any different than them (or, my perception of them, I should say)?

Who knows?  Maybe the symbol is a statement about Pepsi being unequal to Coke.  If that's it, then we could get along and go for a Coke because Pepsi doesn't come close to equaling Coke.
