The word heresy has negative connotations to it. When we hear it, we often have images conjured up of witches burned as heretics, for example. Also, because of it's meaning of a false teaching that can place one's own salvation at risk, it is easy to become defensive, being told xyz is heresy when you personally believe in xyz is, by its very nature, to be told "you are (dangerously) wrong." And no one likes to be told that they are wrong. That being said, in modern apologetics a lot of people try to dance around the H word for the very reason it can be off putting, it can lead to individuals to be less likely to listen to your argument; but it is still important to recognise (at least from a Catholic perspective) when things are heresy.
