How can we use this to our advantage?

I am getting seriously pissed-off (technical expression) with the way people twist what other people say for their own ends.  Defence Secretary Philip Hammond was invited to a discussion with a group of students and the subject of same-sex marriage - to which he is known to be opposed - was raised.  He was asked what right the state has to tell two people who are in love that they can't get married. His reply - well we don't allow siblings to get married.  Well, we don't, do we?  But what's in all the papers?  "Philip Hammond accused of likening gay marriage to incest".  No he didn't!!  He simply pointed out that there were indeed circumstances where the law forbade two people to marry. Just grow up!!
